Pressure Sensor - Industrial - Type KS-I | Gefran

Gefran KS-I Pressure Transmitter

The Gefran KS-I is a pressure transmitter with digital IO-Link v1.1 output, designed for machinery requiring both pressure measurement and diagnostic data from a single sensor. Communication is via COM3 / 230.4 kbaud using an M12 5-pin connector.

Technical Data

Materials and Process Media

The sensing element is a thick film on a stainless steel diaphragm. Wetted parts are suitable for fluids compatible with AISI 430F and 17-4 PH stainless steel. Typical media include hydraulic oils, compressed air, process water, and compatible gases.

Connections and Selection

Available pressure connections: G 1/4" male DIN 3852-E and G 1/2" male DIN 3852-E. Selection depends on hydraulic block port, available installation space, and sealing method.

Applications

Used in industrial automation, compressors, hydraulic power units, plastic injection presses, hydraulic presses, pumps, and multi-sensor pressure monitoring systems.

Standards

Conformity includes RoHS 2011/65/EU, EMC 2014/30/EU, EN IEC 63000:2018, EN 61326-1:2013, EN 61326-2-3:2013.

FAQ

When to select KS-I over KS?
Choose KS-I when the PLC or IO-Link master requires digital measurement, parameterization, and diagnostics instead of 4…20 mA or voltage output.

Does it have an actuator?
No. This is a pressure measurement device; actuation is performed by the PLC, IO-Link master, or machine controller.
