4" Solid Front Blow-Out Back Industrial Pressure Gauge
Model Number 40FS

Accurate, Tough, and Adjustable, Palmer Process Gauges are designed to provide the maximum safety for personnel monitoring the gauges in the event of gauge failure, and to resist the most severe operating conditions created by the ambient environment and the process medium. These gauges are constructed with a solid barrier between the sensing element and the dial front, welded to the socket giving it exceptional strength. In addition to protecting the user from fluid and particles in the event of failure, the backs of these cases are designed to blow out to release pressure inside the case. The 40FS is designed to withstand high overpressure up to 4 times the full scale value. Case and Blow-Out Disk are AISI 304 Stainless Steel in 4" (100mm). Available either filled or dry. Ring is AISI 304, Polished Stainless Steel with Bayonet Connection. Safety Glass is standard. Socket: AISI 316L Stainless Steel, TIG welded to the elastic element using 316 Stainless Steel. Optional K Monel. Bourdon Tube: All Pressure Sensing Elements are made from AISI 316L Stainless Steel. C-tube configuration is used for ranges below 1000 PSI. Spiral tube configuration for higher ranges. Optional K Monel. Connections are 1/2" NPT threads with built in Stainless Steel Restrictor; 1/4" NPT optional. Movement is Stainless Steel with Internal Limit Stops for Minimum and Maximum Pressure. Pointer is balanced black aluminum, micrometer adjustable. Dial is white aluminum with black markings. Markings and graduations in accordance with ASME B40. 1-1998. Process Fluid Temperatures: 212F (100C) maximum for standard tube and socket materials, 450F (230C) maximum for optional K Monel dry gauge. Accuracy is 0.5% of full scale Dry, or 1.0% Filled. Overpressure Limits as a percent of full scale value is 30% for ranges up to 870 PSI (60 Bar); 25% for ranges from 670 to 1400 PSI (100 Bar); 15% for ranges above 1400 PSI (100 Bar). Overpressures in excess of these values may result in a calibration shift but will not damage the movement due to the built in stops. 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). Many Ranges Available.
