ETS 4000 Series

Hydac_ETS 4000HSI_Temp Trans

The ETS 4000 temperature transducers were designed to be fitted directly to the hydraulic system to ensure direct contact with the media for the most accurate and up to date temperature reading. This unit converts the fluid temperature measurement into a usable, 4 to 20mA output signal.

The ETS 4000 has solid construction with all stainless steel wetted parts and tube housing. The transducer hydraulic connection is rated to 8700 psi.

All units are individually calibrated on a computer-controlled test rig and subjected to a final test. The quality system is ISO 9001 certified.
