2-8940-KF25

Pressure Sensors Transducers Overview

The Televac 2-8940-KF25 is a cold cathode ionization active vacuum gauge module designed for pressure measurement. It features an analog output signal ranging from 0 V to 10 V, corresponding to its sensing range of 0.13 PSI (0.93 kPa) gauge pressure. The device operates on a supply voltage between 22 V and 26 V. It is engineered to withstand overpressure conditions up to a maximum limit of 150 PSI (1034.21 kPa). The unit utilizes a connector termination style for interface connections. Its operational environment supports temperatures from 0°C to 50°C, with storage capabilities extending beyond these limits as specified by the manufacturer.
