Bimetal Thermometers with the MAXIVISION® DIAL

Bimetal thermometers from Dresser Instruments broke new ground with the easy-to-read Maxivision® dial. The Ashcroft® Maxivision® dial eliminates parallax error and can be read accurately at many angles.

Bimetal thermometers sense and indicate temperature using the bimetal thermometer coil which consists of two dissimilar metals bonded together. These materials have different coefficients of expansion and, when subjected to temperature change, rotate the coil.

Ashcroft® bimetal thermometers are manufactured at an ISO 9001 certified facility in Stratford, CT to ASME B40.3 Grade A accuracy of 1% of span. The Ashcroft® bimetal thermometers come in 2", 3" and 5" dial sizes and in Fahrenheit, Celsius or dual scale ranges. Various configurations are offered with hermetically sealed cases such as lower, rear or every angle connections with a tamper proof case or an external adjustment, depending on your needs. Standard stem lengths for bimetal thermometers range from 2 1/2 through 24 inches while non-standard stem lengths up to 60 inches can be custom made.

In selecting bimetal thermometers, the following factors must be considered:
Temperature range
Accuracy
Type - dry or liquid
Case size
Window material
Externally adjustable versus tamper proof
Case connection
Stem/connection location
Stem length
