This resistor is used as a shunt to convert a standard 4-20mA analog signal from a field device into a 1-5VDC signal required by certain controller input cards
Precision Modulation: Delivers a consistent 0-15# output for smooth operation of pneumatic control valves and actuators
it provides a reliable normally open circuit that closes upon reaching the specified set point to prove draft and authorize the ignition sequence
leak-free seal in closed-loop systems using hot water
Featuring a precision-engineered 7/64" orifice
