10702523 Murphy Temperature Gauge Model 20BTG-250-4-1/2


The 20BTG-250-4-1/2 B-Series Temperature Murphygage is a 2” dial (51 mm), high-quality,diaphragm-actuatedtemperature-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 morecompact and is the optimum instrument for gage-only applications. Ranges are available from130°-250°F (54°-121°C). Pressure changes at the diaphragm convert to accurate mechanical movementsthat are indicated on an easy-to-read analog dial. A pulsation dampener in the pressure port helpseliminate pointer flutter. It can be removed for cleaning to maintain the gage’s response andaccuracy.instruments are built in the USA, can be utilized in industrial engines and equipment in the oil field, marine, irrigation,construction,and trucking industries as well as monitoring enginecoolant, crankcase oil and transmission oil.
