Step-by-step guide to wire a 4-20mA transmitter to a PID controller: 2-wire/4-wire setups, scaling, and troubleshooting to prevent downtime.
Compare HART vs Modbus RS485 temperature transmitters. Discover which protocol cuts wiring costs, maximizes ROI, and fits your facility layout.
To monitor HVAC filters with a DP transmitter, connect the high-pressure port to a pressure tap upstream of the filter and the low-pressure port to a tap downstream. The transmitter continuously calculates the difference between those two air pressures. As dust accumulates, filter resistance—and usu
Although both are used in HVAC systems, HVAC refrigerant and air differential pressure transmitters measure different variables and cannot be interchanged. A refrigerant pressure transmitter normally measures gauge pressure at one point in a sealed refrigerant circuit. An air differential pressure t
Maximum reference error = Full-scale span × 0.00075When a differential pressure transmitter is specified with 0.075% FS accuracy, its maximum reference error is typically plus or minus 0.075% of the stated full-scale span under defined reference conditions. For a 0–100 kPa range, the calculation is
