X623 Submersible Large Angle Tilt Sensor

ATEX & IECEx approved intrinsically safe underwater sensor for hazardous gas environments


About the X623 Submersible Large Angle Tilt Sensor

The intrinsically safe 350 bar X623 tilt sensor is ATEX and IECEx approved for use in potentially explosive gas/vapour atmospheres. It is designed for continuous underwater applications and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas. The X623, like all Positek sensors, is supplied with the output calibrated to the angle required by the customer, between 15 and 160 degrees and with full EMC protection built in. The sensor provides a linear output characteristic with angle of deflection. There is a machined registration mark to identify the calibrated mid point.

Overall performance, repeatability and stability are outstanding over a wide temperature range.

It is sealed to IP68 350bar (5000psi, 3500m depth).

The sensor has a rugged stainless steel body and mounting flange.

Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier. Approved galvanic isolation amplifiers (X005) 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.
