Part no.: G133
• CSA approved to: Class I, Zone 0
• Sensor Mounting: Flange or body clampsSpring loaded pushrod option available
• Available in any measurement range from 0-51mm to 0-100mm(for 2-50mm range see P103)
• Sealed to IP65/67 depending on connector/cable option
The intrinsically safe G133 is CSA approved for use in potentially explosive gas/vapour atmospheres. It is designed for a wide range of industrial applications and is ideal for OEMs seeking good sensor performance in situations where a mid-bodied sensor is required for operation in hazardous areas. The unit is compact and space-efficient, being responsive along almost its entire length, and like all Positek sensors provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 0-51mm to 0-100mm and with full EMC protection built in.
Overall performance, repeatability and stability are outstanding over a wide temperature range.
The sensor has a rugged stainless steel body and plunger. It is easy to install and set up, mounting options include flange and body clamps. The plunger can be supplied free or captive, with female M4 thread, or spring-loaded with a ball end. The G133 also offers a wide range of mechanical options, environmental sealing is to IP65 or IP67 depending on selected cable or connector options.
Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier. Approved galvanic isolation amplifiers (G005) 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.
Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications between a master (i.g. controller) and a slave (i.g. sensor).
While most modern rotary encoders rely on non-contact sensing technologies and have high MTBF specifications, in critical applications it is still common to have redundant sensors required. When selecting a solution, a number of different criteria need to be considered and fortunately different solutions exist, making the task less daunting. Redundancy One of the first […]
All absolute rotary encoders have a rotor which is attached to the rotating shaft and a stator which is attached to the housing holding the shaft. The interaction of these two components produces a measure of the shafts rotational angle. The most important parameters of absolute rotary sensors are resolution, accuracy and tolerance to misalignment of the rotational axes.
In this example, the switch point has been set to ‘Full Alarm’. By setting the switch point to 90% with an 80% hysteresis, the switch will come on at 90% and switch off at 10%.
