Absolute pressure

is measured inside the cost effective, practical and robust standard housing. The technical design enables the on site changeover of the measuring range, as well as the choice of the output signal. This universally applicable sensor is the right solution for price conscious customers. It distinguishes itself through its low maintenance and easy operation.

Cost effective
OEM variant with three modes of operation
For use with data loggers in power saving mode (e.g. solar operation)
One device with two pressure measuring ranges and three standard outputs; adjustable via jumpers
