Siemens 173S-M44 Pneumatic Pressure Transmitter

Technical SpecificationsModel:173S-M44 Brand:Siemens Product Type:Pneumatic Pressure Transmitter Input Pressure Range:1100-1400 psi Output Signal:3-15 psi pneumatic Supply Air:20-100 psi clean dry instrument air Mounting:Field pipe / surface mount Operating temperature:-20℃ ~ +70℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~95%, non-condensing Weight:2.2kg Dimension:140mm180mm220mm

System compatibility173S-M44 belongs to Siemens Moore 173S pneumatic transmitter series. It outputs pneumatic 3-15psi signal, compatible with pneumatic controllers, valve positioners, and can work with APACS+ and QUADLOG systems via I/P converters.

FunctionThis 173S-M44 pneumatic pressure transmitter measures process fluid or gas pressure. It senses the process pressure and converts the measured value into standard 3-15psi proportional pneumatic signal. The pneumatic signal transmits pressure measurement to pneumatic control equipment for pressure monitoring and closed-loop regulation in process plants.

InstallationIsolate process pressure and instrument air before installation. Mount transmitter at pressure tapping point, connect process pressure inlet. Hook up clean instrument air supply and pneumatic signal output tubing. Perform zero and span calibration after pipeline stabilizes, verify output pressure response.

InterfaceProcess pressure port, instrument air supply port, pneumatic signal output port, zero and span adjustment screws.

FeatureMoore 173S mechanical pneumatic transmitter, all pneumatic design, no electric power required, rugged cast housing, on-site calibration, suitable for hazardous areas. Obsolete legacy spare part, used for old pneumatic pressure measurement loop maintenance and replacement.

DiagnosticNo pneumatic output: check instrument air supply, filter blockage, process isolation valve status. Output pressure drift: re-calibrate zero and span, inspect diaphragm and bellows for leakage. Slow response: check tubing blockage, condensate accumulation in signal pipe.

Product BriefSiemens 173S-M44 is Moore 173S series field pneumatic pressure transmitter, widely used in petrochemical, power and pulp & paper industries for pneumatic pressure measurement loops.
