WEISS

The WEISS adjustable-angle digital thermometer line covers a temperature range of -50°F to 300°F (-40°C to 150°C) for most models, with some variations such as -45°C to 150°C. Accuracy is specified as ±1% or ±1°F, whichever is greater. These instruments feature a water-resistant construction and an NPT thread for direct mounting into tanks or pipelines. Stem lengths include 3.5-inch, 4-inch, and 6-inch options, depending on the model. The adjustable-angle head allows the display to be rotated for readability after installation. This makes the digital line suitable for outdoor or wet environments where a local digital readout is preferred over a mechanical dial.

WEISS brass thermowells are available with different pressure and temperature ratings depending on the model. For example, the B35-75BSLF straight-shank threaded thermowell is rated to a maximum operating pressure of 5,000 psi at 70°F and a maximum operating temperature of 400°F (204°C). Another model, the E35-75BSLF, is rated to 604 psi at 70°F and 800°F (427°C). These ratings reflect the specific construction and intended service conditions. When selecting a thermowell, verify that the pressure and temperature limits meet or exceed the process conditions, and confirm the stem length and diameter match the thermometer being installed.

WEISS digital thermometers are offered with stem lengths of 3.5 inches, 4 inches, and 6 inches. All models in the adjustable-angle water-resistant line use NPT thread type for installation. The thread size is not specified in the general product data, but NPT threads are standard for pipe and tank mounting. The stem length should be selected based on the insertion depth required for accurate measurement and the thickness of the vessel wall or pipe fitting. For thermowell installation, the stem length must match the thermowell's designated stem length to ensure proper fit and thermal contact.

The WEISS analog panel mount dial thermometer has a 6-inch dial diameter and an accuracy of ±1% of scale division. The model 60BL4-5231-40/240F covers a temperature range of 40°F to 240°F. This type of thermometer is designed for panel mounting, where the dial is read directly from the front of a control panel or enclosure. The 6-inch dial provides a larger scale for easier reading at a distance. Accuracy is expressed as a percentage of the scale division, which is a common specification for mechanical dial thermometers. This model is suitable for general-purpose temperature monitoring in industrial panel applications.

Yes, WEISS thermometers are designed to be used with thermowells for applications where the sensing element must be isolated from the process fluid or where the thermometer needs to be removed without shutting down the process. The thermowells are straight-shank threaded types, available in brass, with specific stem lengths and diameters. For example, thermowells are offered for 3.5-inch stem lengths and 1/2-inch or 5/8-inch stem diameters. When pairing a thermometer with a thermowell, the stem length and diameter of the thermometer must match the thermowell's specifications. The thermowell's pressure and temperature ratings must also be compatible with the process conditions.

The maximum operating temperature for WEISS thermowells depends on the specific model and material. For the brass thermowell model B35-75BSLF, the maximum operating temperature is 400°F (204°C). For model E35-75BSLF, the maximum operating temperature is 800°F (427°C). These ratings are based on the construction and are independent of the pressure rating, which also varies by model. When selecting a thermowell, both the pressure and temperature limits must be considered for the intended application. Operating above the rated temperature may affect the mechanical integrity of the thermowell and the accuracy of the temperature measurement.
