How to Monitor HVAC Filters with a Differential Pressure Transmitter

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

HVAC Refrigerant Pressure Transmitter vs Air Differential Pressure Transmitter

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

What Does 0.075% Accuracy Mean for a Differential Pressure Transmitter?

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

1-Inch vs 1.5-Inch Tri-Clamp Pressure Transmitters

Choosing between a 1-inch vs 1.5-inch Tri-Clamp pressure transmitter is not simply a matter of picking the number printed on an existing pipe. The correct size depends on the sanitary connection standard, actual ferrule dimensions, tube bore, diaphragm geometry, process medium, and cleaning conditio

How to Properly Install a Flow Meter?

How to Properly Install a Flow MeterThe accuracy and reliability of a flow meter largely depend on its installation quality. Flow meters are often installed in industrial environments with space constraints, vibration, or temperature variations. Proper installation is essential to ensure precise measurement and long service life.
