Does this transducer require field calibration after installation

the DPT2090-100G is calibrated for positive 0-100 Psig input and is not rated for continuous vacuum service

This automatic reset limit switch features a cut-out temperature range of 225°F to 275°F

and 371 GPH at 5' to maintain optimal saturation in medium-to-large media pads

making it suitable for standard commercial voltages

Carrier HH12ZB150 Limit Switch R-134A Does this transducer require fieldThe Carrier HH12ZB150 Limit Switch is a critical OEM safety component designed for precise thermal monitoring in high output furnace applications and residential air handlers. As a genuine Carrier L150F 40 temperature control, this switch is engineered to maintain system integrity by automatically interrupting the electrical circuit when internal plenum temperatures reach the 150F set point. This proactive thermal cutout prevents heat exchanger damage
