Barksdale offers indoor use remote and local mount temperature switches with NEMA 4 and/or explosion proof design. All switch options are available with one or two adjustable temperature set points, fixed or adjustable hysteresis, and a wide range of operating temperatures.
Barksdale offers indoor-use remote and local mount temperature switches with one or two adjustable temperature set points and fixed or adjustable differential. The guide describes NEMA 4 and 13 leak-proof designs, optional NEMA 7 and 9 explosion-proof construction, threaded conduit connections, and stainless steel or copper capillary tubes in standard 6 ft or 12 ft lengths, with custom lengths available.
It explains local-mount sensing, where fill fluid surrounds a bellows, and remote bulb and capillary sensing that allows the switch enclosure to be placed up to 25 ft above the liquid level. It also covers ambient temperature compensation, differential tolerances, hermetically sealed switch elements, electrical ratings, and temperature conversion tables. This manual is written in Chinese.

It indicates a leak-proof design.
Up to 25 feet above the liquid level.
Barksdale states that its bulb and capillary configuration provides ±1% accuracy with ambient compensation.
Choose a range so the required set point falls within 60% of the adjustable range.
