H100 Cylinder Linear Position Sensor


CSA Approved Intrinsically Safe sensors for Hazardous GAS atmospheres
Available in any travel from 5mm to 800mm.



The Positek H100 LIPS® (Linear Inductive Position Sensor) incorporates electronics system EX06 which is CSA approved for use in potentially explosive gas/vapour and dust atmospheres. The H100 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, repeatability 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 H100 provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 5mm to 800mm and with full EMC protection built in.


The sensor is very rugged, being made of stainless steel with an inert fluoropolymer-sheathed probe with the option of either an aluminium or 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.

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 5mm to 800mm in increments of 1mm.
For example, if your application requires 10" (254 mm) measurement
then Positek will manufacture the sensor specifically for this length.
The mechanical length and calibration will be set up for 254 mm.


Connector/Cable Options:

Option code
Connector, IP67, M12 - 4 pin.
J
Cable Gland, IP67
L
Cable length - The standard length of cable supplied with a Positek position sensor is 50cm although you can specify any length you require, up to a maximum of 15000cm.
Specified in cm after the L
e.g. L200 for 200cm cable
