Its rugged steel case, break-resistant polycarbonate lens, and corrosion-resistant design ensure durability in demanding industrial environments. Featuring a 4-foot sealed capillary tube and self-cleaning switch contacts, this instrument delivers reliable, maintenance-friendly performance for professional temperature control applications. ## Description The 20T-250-4-1/2 is a 2" Temperature Swichgage. This very popular design features a diaphragm-actuated, temperature-indicating gage, with a built-in electrical switch for tripping alarms and/or shutdown devices. This model has a 4 foot capillary length with a standard 1/2-14 NPT threading, and a temperature range from 130-250°F (54-121°C). The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break-resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument. This vapor actuated gage features a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading. Inside the 20T-250-4-1/2, the gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are grounded through the Swichgage case. This gage has a self-cleaning motion to enhance electrical continuity. ## Features - Built-In Electrical Switch for Tripping Alarms and/or Shutdown Devices ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07S8YVFLX | | Best Sellers Rank | 361,839 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 876 in Temperature Controllers | | Brand | Murphy by Enovation Controls | | Item Dimensions | 7.6 x 91.4 x 7.6 centimetres | | Item dimensions L x W x H | 7.6 x 91.4 x 7.6 centimetres | | Manufacturer | Murphy by Enovation Controls | | Manufacturer Part Number | 20T-250-4-1/2 Temp.
