Transpak TP670-0009 NSMD Frequency Input Transmitter

The TRANSPAK TP670-0009 NSMD Frequency Input Two-Wire Transmitter converts low-frequency pulse signals into a standard 4–20 mA current loop for industrial process control. With a 0–30 Hz input range and an adjustable span down to 15 Hz, it accepts frequency or pulse inputs and delivers a two-wire 4–20 mA signal for reliable transmission. Designed for non-isolated signal handling in rugged industrial field environments, the unit features a die-cast aluminum housing and is commonly installed with magnetic pickups, turbine flowmeters, velocity sensors, digital meters, and process monitoring equipment. Applications span flow and velocity measurement, process instrumentation, limit alarms, and system retrofits where a low-frequency pulse must be converted to a standard 4–20 mA signal; maintenance teams, OEMs, and system integrators rely on it for instrumentation repair, signal conversion, control system retrofit, and replacement of existing frequency transmitters. NSMD reference marking identifies compatible replacements, including TRANSPAK TP670-0009, ACTION INSTRUMENTS T670-0009, and EUROTHERM T670-0009.
