Pressure switch features various ranges

Pressure switch from Turck has an operating range to 400 bar.

Accurate detection and display of system data is essential for optimizing process control. Turck, Plymouth, Minn., has introduced a versatile range of pressure switches that combine a sensitive piezoresistive measuring cell, microprocessor-based display, evaluation electronics, and a user-friendly operator interface.

The system is suited for relative pressure measurements, with operating ranges from 0 to 10, 40, 100, and 400 bar. The operating and display panel provides online pressure monitoring via a four-digit, seven-segment display; bargraph (10 LED) of active measuring range; programming and display in bar or psi; and identification of the two preset switching points. The pressure switches operate with 10 to 30 Vdc. Outputs are two-transistor pnp, short-circuit protected 200 mA.
