G502 Small Angle Rotary Sensor


CSA Approved Intrinsically Safe sensors for Hazardous GAS atmospheres
Available in any travel from 5° to 15°


The Positek G502 RIPS® (Rotary Inductive Position Sensor) incorporates electronics system EX06 which is CSA approved for use in potentially explosive gas/vapour atmospheres. The G502 is designed for industrial and scientific feedback applications, like the G500 but with better resolution at smaller angles of deflection, and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas.


The G502, like all Positek® sensors, provides a linear output proportional with angle of rotation. Each unit is supplied with the output calibrated to the angle required by the customer, between 5 and 15 degrees and with full EMC protection built in.

There is a machined registration mark to identify the calibrated mid point.


Overall performance, repeatability and stability are outstanding over a wide temperature range. The G502 has long service life and environmental resistance with a rugged stainless steel body and shaft. The flange or servo mounting options make the sensor easy to install, it also offers a 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.

CSA approval

CSA approved to; Class I, Zone 0 Ex ia IIC T4 (Ta = -40°C to +80°C) AEx ia IIC T4 (Ta = -40°C to +80°C) Designates the sensor as belonging to; Class I, Zone 0: suitable for all areas except mining, : can be used in areas with continuous, long or frequent periods of exposure to hazardous gas / vapours. Protection class ia IIC, denotes intrinsically safe for Zones 0, 1 & 2 and IIA, IIB and IIC explosive gases. Temperature class T4: maximum sensor surface temperature under fault conditions 135°C. Ambient temperature range extended to -40°C to +80°C. Approval only applies to the specified ambient temperature range and atmospheric conditions in the range 0.80 to 1.10 Bar, oxygen <=21%.

Galvanic Isolation Amplifier

It is imperative Positek® intrinsically safe sensors be used in conjunction with a galvanic barrier to meet the requirements of the product certification. The Positek G005 Galvanic Isolation Amplifier is purpose made for Positek IS sensors making it the perfect choice. Refer to the G005 datasheet for product specification and output configuration options.


The Positek® G005 Galvanic Isolation Amplifier is available with 0.5 - 9.5V or 4 - 20mA transmission output options or reverse outputs of 9.5 - 0.5 volts or 20 - 4 mA.

Preferences

Positek offers a range of options for its standard sensors.
Each sensor is manufactured to suit each customer's preferences.
If your requirement is outside the options given below,
Positek can modify/ redesign a sensor to suit your specific requirement.
Standard options are available as below:

 

Measurement range:

Factory set to any angle from ±2.5° to ±7.5° in increments of 1°
For example, if your application requires 10° measurement
then Positek will manufacture the sensor specifically for this angular range. The sensor will measure 10° however will still rotate through 360°.
