Opkon potentiometers and linear sensors combine reliable sensing at an economic price. With a broad number of mechanical housings available, Opkon sensors are easy to adapt to new and exsisting designs alike.
Tracing its origins to 1918, POSITAL has a long history in the sensor business. Offering rotary encoders, linear drawwire and contact-measuring wheels and inclinometers along with custom design services for small projects and OEM’s, POSITAL will work with you to find or create the solution for your sensing needs.
Positek’s inductive technology combines the robustness and performance of an LVDT with a simple analog output interface and a reduced form factor. Available in linear, rotary and tilt sensors, some Positek sensors are also rated by ATEX and CSA for hazardous environments.
Trumeter offers local display options as well as remote ‘cloud’ based monitoring for sensor and process control. Unlike other in the market who require a 3rd party programmer and expensive monthly cellular fees, Trumeter offers easy to use interfaces all at a very reasonable cost.
Zettlex (Celera Motion) offers robust inductive based rotary encoders. As an alternative for traditional resolvers, Zettlex ‘IncOders’ offer a much more compact form factor as well as common industry communication protocols.
We represent a wide range of manufacturers specializing in rotary encoders. Our extensive selection ensures that we can find the perfect solution for your needs.
Linear sensors come in all different shapes and sizes and at Everight we are here to help navigate through the seemingly overwhelming number of options. Whether you are measuring fractions of an inch or hundreds of feet, Everight offers a unique variety of LVIT’s, potentiometers, draw wires and contact measuring wheels.
In its simplest form a rotary encoder provides information on the position or motion of a shaft. Multi Turn encoders can also provide information on the number of turns. While traditional contact based potentiometers are still appropriate for some basic applications, most modern control systems rely on optical, magnetic, capacitive or inductive technology for robust, reliable and high resolution sensing.
Inclinometers, also called tilt sensors, are designed to measure the angle of an object with respect to the force of gravity. These tilt or level meters determine pitch and/or roll angle and output these values via the appropriate electrical interface. Inclinometers are easy to integrate into an application because there is no need for mechanical linkages other than just the installation itself – a real advantage for design engineers.
Gill is a world leader in capacitive, solid-state liquid level sensing technology. With no moving parts to break or wear out, Gill liquid level sensors offer unmatched long term reliability in a variety of harsh environments.
The Gill WearDetect Oil Debris Sensor is proven in use by some of the world’s leading manufacturers, to provide the earliest warning of the initial stages of machine failure.
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.

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.
Full instructions can be viewed here: https://www.positek.com/contentfiles/files/Linear_Calibration_Instructions.pdf
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.
