40ES Current Loop Transmitter Gauges
Model Number 40ES

The reliability of a mechanical gauge with the interface flexibility of an electronic sensor. Case is AISI 304 Stainless Steel in 4" (100mm). Available Dielectric Fluid or Dry. Ring is AISI 304 Polished Stainless Steel. Bayonet connection. Window is Laminated Safety Glass. Socket is AISI 316 Stainless Steel. Pressure Sensors: Bourdon tube is made from AISI 316L Stainless Steel. Electronic sensor is thick film on ceramic, seal is PTFE (Teflon). Sensors rae completely independent of one another giving the instrument a built-in back up and calibration check capability. Connection is 1/2" NPT, 1/4" optional. Movement is reinforced stainless steel. Pointer is balanced black aluminum, micrometer adjustable. Dial is white aluminum with black markings. Markings and graduations in accordance with ASME B40.1-1998. Temperature Limits: -4F to 150F for Filled Gauge (ambient and process fluids). Overpressure limits as a percent of full scale value: 30% for ranges up to 870 PSI (60 Bar), 25% for ranges from 870 to 1400 PSI (100 Bar), 15% for ranges above 1400 PSI (100 Bar). Optional 200% over range (changes accuracy to 1% of full scale). Accuracy is 0.5% of full scale value (ASME grade 2A) on Dry Gauges, 1.0% (ASME grade 1A) on Filled Gauges. Temperature Errors: For a normal temperature of 68F (20C), approximately +0.3% error for a temperature increase of 18F and -0.3% error for a temperature decrease of 18F (10C). Transmitter Specifications: Output signal is industry standard 4 to 20mA current loop. Power supply is 18 to 32 volts, 25 mA. Accuracy is 0.5% of full scale value including linearity and hysteresis. Operating Temperature Range is -13 to 160F (-25 to 85C). Compensated Temperature Range is 14 to 104F (-10 to 40C). Temperature Effect on Zero Balance is less than 0.02% F (0.03% C), in the compensated range. Temperature Effect on Output is less than 0.006% F (0.01% C) in the compensated range. Long Term Stability is typically less than 0.01% per year. Additional options are available. Contact Customer Service for assistance regarding options and ordering.
