Tax included

The electronic PREMASREG® 761x - VA pressure sensor and switch is equipped with measuring functions for volume flow, differential pressure, filter monitoring and liquid level detection based on pressure measurement in clean air. The devices feature a V4A stainless steel housing, a cable gland or M12 connector according to DIN EN 61076-2-101 and a stainless steel quick-connect pressure port (pipe fitting optional). They provide one switching output, one continuous output and a back-lit display for setting the switching point and showing actual values. The piezoresistive measuring element guarantees a high degree of reliability and accuracy.
