20BTG-250-35-1/2 Temperature Murphygage (10702586)

20BTG-250-35-1/2: 2" B-Series Temperature Murphygage, 130-250¡F temp range, 35 ft capillary length (10702586)

The B-Series Murphygage instrument is a high-quality, diaphragm-actuated indicating gage. Built by Enovation Controls with the same heavy-duty design as the standard 20 series and 25 series Swichgage instrument, the B-gage is more compact and is the optimum instrument for gage-only applications.

It has a high impact polycarbonate lens, sturdy steel case and a polished, low-profile stainless-steel bezel. Accuracy and protection from moderate over-pressure/overtemperature are assured by a unique, unitized diaphragm chamber, superior quality materials and the design of the gage movement.

Pressure changes at the diaphragm convert to accurate mechanical movements that are indicated on an easy-to-read analog dial. A pulsation dampener in the pressure port helps eliminate pointer flutter. It can be removed for cleaning to maintain the gageÕs response and accuracy.

As temperature rises, the fluid in the sensing bulb vaporises to apply pressure on the diaphragm. The movement translates this vapor pressure to a calibrated reading of temperature on the dial.
