Tags: TEMPERATURE SWICHGAGE


The 4-1/2” (114 mm) size dial Swichgage 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.

Panel and wall-mount versions are available as well as latching control relay versions.

Ranges are available from 15° to 250°F (9° to 121°C) through 260° to 450°F (127° to 232°C).

Typical applications include:

Gas compressors

Heaters and coolers

Water pump temperature

Engine coolant temperature

Process temperature

Basic Models

SPLC Series Swichgage: Surface-mount version of the Swichgage. For these models the gage pointer makes with two adjustable contacts to complete a pilot-duty circuit.

SPLFC Series Swichgage: Panel-mounting (round case) version of the SPLC.

SPLBP Latching Control Relay Swichgage: This version of the SPLC Series is designed to start and stop electric motor driven equipment. The pilot-duty contacts of the SPLBP are connected to a latching control relay for automatic ON/OFF control, either directly or through a motor starter.

45TE Series Snap-Acting Swichgage: Surface-mount version of the Swichgage. These models offer internal snap-acting SPDT switches, instead of the single pole contacts.

45TEF Series Swichgage: This is the panel-mounting (round case) version of the 45TE series.

45TEBP Snap-Acting and Latching Control Relay Swichgage: Same as 45TE – includes an internal latching control relay for automatic ON/OFF control either directly or through a motor starter.

We offer square case configurations altered to fit round panel openings, see Dimensions.

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 and SPLFC, 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.
