- 250 = 15° - 250° F (9° - 121° C)
- S = Stainless Steel
- 05 = 5 Feet Capillary Length
- EX = Explosion-Proof; Gage Enclosed Within Explosion-Proof Case; Class I, Division I, Groups C And D E
The 4-1/2” (114 mm) size dial gage is a mechanical gage for temperature indication. It is a combination indicating gage and critical temperature limit switches. High and low temperature limit contacts are visible.
It includes adjustable, electrical contacts that can be used for start and stop, to trip alarms and to shut down equipment.
Typical applications include:
- Gas compressors
- Heaters and coolers
- Water pump temperature
- Engine coolant temperature
- Process temperature
Basic Operation
This vapor-actuated gage features a sealed capillary tube and sensing bulb. When subjected to heat, the liquid in the sensing bulb expands to vapor creating pressure against a bourdon tube mechanism. The bourdon tube translates this vapor pressure into a mechanical gage reading.
For models SPLC, the gage pointer acts as a pressure indicator and as one switch pole, which completes a circuit when it touches the adjustable limit contacts. Contacts have self-cleaning motion to ensure electrical continuity. A toggle switch is provided on SPLC models to override the low contact for equipment start-up.
