Differential Pressure Transmitters Additional Information

Mid-West Instrument differential pressure gauge/transmitter provides the customer a real time 4-20 ma signal of  the process conditions. Our Transmitter whether it be an indicating or non-indicating differential pressure transmitter is a 2 wire loop powered microprocessor based 4-20 ma transmitter. The magnetic angle sensor & electronics senses the angle (relative to the transmitter sensor) of the magnet which moves linearly in the bore. Each transmitter is individually calibrated to the gauge using an 11 point calibration linearization technique. This method results in a  <2% accuracy for the upper 80% of the range. External zero pin is available for simple zeroing after installation.

Mid-West Instrument 4-20 mA Transmitter (8-28 VDC Loop Power) is available standard with a NEMA 4X enclosure and a 4 position terminal strip. Additional options include CE marking to RoHs and EMC directive, Hazardous Locations ratings for Div 1 and Div 2 locations and ATEX ratings for Category 2 locations. For complete safety ratings or certifications refer to our individual model Specifications Sheets.
