These differential pressure transmitters are available in piston and diaphragm sensor models rated from 1,500 to 5,000-psig line pressures.While piston models cover differential pressure ranges of 0 to 5 and 0 to 1,000 psid, diaphragm models cover differential pressure ranges of 0 to 5 and 0 to 300 psid. Users simply select the output desired, whether voltage, current, frequency or RS232 output. Built-in temperature compensation ensures that the output of the transmitter does not drift. Each transmitter can be installed as a three- or four-wire connection. Optional dials for local readout can include dual scales, follower pointers, red or multi-color arcs, and other choices to meet specific requirements. In addition, other piston and diaphragm sensor transmitter models are available to meet specific line pressure and differential pressure range requirements.
