G133 Mid Stroke Linear Position Sensor


CSA Approved Intrinsically Safe sensors for Hazardous GAS atmospheres
Available in any travel from 51mm to 100mm.


The Positek G133 LIPS® (Linear Inductive Position Sensor) incorporates electronics system EX06 which is CSA approved for use in potentially explosive gas/vapour atmospheres. The G133 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 51 to 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.

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 length from 51mm to 100mm in increments of 1mm.
For example, if your application requires 3" (76 mm) measurement
then Positek will manufacture the sensor specifically for this length.
The calibration will be set up for 76 mm.
