While finding the right sensor solution for ‘Hazardous Environments’ may be more complicated, it doesn’t mean that it can’t be done. Everight can’t replace a Safety Engineer, but Everight can help navigate linear, rotary sensor and inclinometer sensors that have been formally rated for use in hazardous environments to ATEX, IECEx and CSA requirements.
The P101 is a durable, affordable, high accuracy stand alone linear inductive position sensor designed for use in scientific and industrial applications.
Like all Positek sensors the P101 provides a linear output that is proportional to the displacement. The P101 is very compact and offers an excellent stroke to overall length ratio. Each unit is supplied calibrated to the exact travel required by the customer, for example, if your application requires 10″” (254 mm) measurement then Positek will manufacture the sensor specifically for this length.The mechanical length and calibration will be set up for 254 mm.the P101 is available with any travel from 0-5mm to 0-800mm.
The overall performance, repeat-ability and stability are outstanding over a wide temperature range. The sensor is very robust, manufactured from stainless steel the P101 has a long service life and strong environmental resistance and is particularly suitable for applications that require good sensor performance in harsh environments such as industrial machinery where cost is important.
The P101 is easy to install with either M5 rod eye or body clamps. The push rod can be supplied captive or free with either M5 thread, M5 rod eye or ball end. The rod can be spring loaded if required in either direction on sensors with a stroke length of up to 300mm. The P101 is available with a wide range of electrical inputs/outputs, sealing up to IP65/IP67 dependent on connector/cable options and fully integrated EMC protection.
The intrinsically safe X132 is ATEX and IECEx approved for use in potentially explosive gas/vapour atmospheres. It is designed for gauge head positioning in industrial and scientific applications and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas. The X132, like all Positek sensors, provides a linear output proportional to displacement. Each sensor is supplied with the output calibrated to the travel required by the customer, from 0-5mm to 0-50mm and with full EMC protection built in.
Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is very robust, the body and plunger being made of stainless steel for long service life and environmental resistance.
The plunger is spring loaded with a domed end. The X112 is easy to install with a long ½ inch UNF mounting thread and is supplied with two lock nuts for positioning. Environmental sealing is to IP67.
Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier . Approved galvanic isolation amplifiers (X005) are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.
The sensor can be installed with a cable length up to 1km between the sensor and the amplifier.
The P132 is a very compact, durable, affordable, high accuracy linear inductive position sensor with a good stroke to overall length ratio; designed for gauge head positioning in scientific and industrial applications.
Like all Positek sensors the P112 provides a linear output that is proportional to the displacement. Each unit is supplied calibrated to the exact travel required by the customer, the P112 is available with any travel from 0-5mm to 0-50mm. For example, if your application requires 3/4″””” (19 mm) measurement then Positek will manufacture the sensor specifically for this length. The calibration will be set up for 19 mm. The overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is very robust, manufactured from stainless steel the P112 has a long service life and strong environmental resistance and is particularly suitable for applications that require good sensor performance in harsh environments such as industrial machinery where cost is important.
The P112 has a spring loaded plunger with a dome end and the body has a long 1/2″””” UNF mounting thread and is supplied with two lock nuts for positioning. Sealing is IP67 and the P112 has fully integrated EMC protection.

Netzer VLS encoders are ideal for LEO space applications.Space rated with TID 30krad and paralyene conformal coating, the open frame, 2 plate design, the sensor is lightweight, highly tolerant to temperature, shock, EMI, RFI and magnetic fields. Options include VLS-60, VLS-80. VLS-100, VLS-140 and VLS-170
The POSITAL UCD-…-H200 series is a robust, flexible alternative to geared potentiometers such as the GP09. Rather than relying on a contact-based potentiometer, the H200 uses an internal non-contact based Hall-effect sensor. This provides not only more reliable readings, but the flexibility to scale the output range during installation.
POSITAL UCD analog encoders are a novel alternative to traditional rotary encoders. Relying on a non-contact Hall sensor, UCD encoders are scalable by the end user, offer 13 bit resolution and multiturn counting.
IncOder CORE 70mm is a non-contact, lightweight absolute rotary inductive encoder fully contained in a printed circuit board kit. The hollow bore design is suited for integration into rotary actuators. The position sensor utilizes a unique field-proven inductive technique, delivering highly repeatable, reliable, temperature-stable measurement performance.
POSITAL CCD Hollow Shaft Kit Encoders are ideal for Integration to motors, robot joints and other challenging installations. A large 30mm through hollow shaft diameter and a battery-free Weigand based multiturn counter make this sensor as unique as the applications it is used on.

I thought rotary encoders used optical discs, but now I’m finding other options such as magnetic, capacitive and inductive. How do I determine which is right for my application?
Each sensor technology has its own strengths and weaknesses and within each technology there is a broad range of options. For example, some optical encoders cost $20 and others cost $10,000. The chart below is a very generalized overview of how the different technologies stack against one another and it should be noted that exceptions do exist.

Incremental Encoders
Incremental devices provide position change information only, so the actual position (0-360°) is unknown at startup. A once-per-rev index/marker signal defines the zero position or null of the device. It can be detected during a homing routine if needed.
Incremental sensors are typically small, accurate and cost-effective. They provide essentially instantaneous position information with minimal latency.
Absolute Encoders
Absolute devices provide the actual physical position within one revolution. Homing elimination is a major advantage as this process takes time and isn’t always possible depending on the physical limits of the application.
Absolute sensors are usually bigger and more expensive than incremental devices. Data processing of multiple tracks and serial transmission can increase the latency of position reading. Absolute sensors are available in a wide variety of interfaces including analog (voltage, current), SSI, BiSS, CANopen, J1939 and many Ethernet based protocols.
Absolute Multi-Turn
Rotary, multi-turn devices provide actual position over multiple revolutions. Homing can be eliminated. Multi-turn devices incorporate internal gearing, a battery backup or a self-generated pulse counter such as a Weigand Wire.
While Positek sensors are manufactured to never need to be calibrated, we do understand that sometimes it can be necessary to confirm the sensors functionality and linearity.

Note, you will need a sensor where the ‘trim pots’ are accessible to make this adjustment.
If it is a Gill liquid level sensor, yes you can. Some lower-end capacitive sensors rely on the tank housing to complete the circuit necessary to measure the liquid level, however Gill liquid level sensors are fully enclosed, and thus can be used in tanks made of any material. Gill sensors can even be mounted at an angle or upside down with no loss of performance.
