Intrinsically safe H130 is CSA approved for use in potentially explosive gas/vapour and dust atmospheres. The H130 is designed for demanding hydraulic or pneumatic cylinder position® feedback applications where service life, environmental resistance and cost are important and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas.

Overall performance, repeat-ability and stability are outstanding over a wide temperature range. The unit is highly compact and space-efficient, being responsive along almost its entire length. Like all Positek sensors, the H130 provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 0-400mm to 0-1485mm and with full EMC protection built in.

The sensor is very rugged, being made of stainless steel with an inert fluoropolymer-sheathed probe and stainless steel target tube. The sensor is easy to install in cylinders and has a range of mechanical options. Environmental sealing is to IP67.

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.

Intrinsic Safety

CSA Approval

This sensor is 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)
AEx iaD IIIC T93°C(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 or dust

Gas:
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.

Dust:
T93°C: maximum sensor surface temperature under fault conditions 93°C.
Ambient temperature range extended to -40°C to +80°C.

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.

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 0-400mm to 0-1485mm in increments of 1mm. For example, if your application requires 40" (1016 mm) measurement, then Positek will manufacture the sensor specifically for this length. The mechanical length and calibration will be set up for 1016mm.
