Dial Thermometers replace liquid-in-glass units.

Press Release Summary:

Slip-Fit bi-metal dial thermometers slip into existing thermometer thermowells and fit by tapered bulb chamber. Cases, bezels, and stems are constructed from polished 304 stainless steel. Either 3 in. or 5 in. high-visibility, anti-parallax dial sizes are available. Stem lengths from 3.5 to 12 in. are offered. Slip-Fits utilize 1-1/4 in. - 18 plated brass swivel nut fitting. Temperature ranges from -100°F (-50°C) to 1000°F (5000°C) are available in °F or °C scales.

Original Press Release:

Palmer "Slip-Fit" Bimetal Dial Thermometers from the Instrumentation Group

Palmer Instruments, Inc. of Asheville, NC offers a bimetal dial thermometer designed as a quick, cost-saving replacement for Industrial liquid-in-glass type units, with no accuracy loss.

"Slip-Fit" dial thermometers are designed to "slip" into existing Industrial thermometer thermowells and "fit" by means of a tapered bulb chamber. The tapered bulb provides the
identical metal-to-metal contact and resulting heat transfer as the replaced Industrial-type thermometer, but without the possibility of glass tube breakage and resulting liquid fill

Slip-Fit cases, bezels, and stems are constructed from polished type 304 stainless steel. Either 3" or 5" high-visibility, anti-parallax dial sizes are available. Two case styles are offered: back connected or versatile All Angle that adjusts to virtually any viewing angle. Cases are hermetically sealed at the factory to seal out moisture and prevent icing and coil freeze-up. Slip-Fits utilize a 1-1/4" - 18 plated brass swivel nut fitting, again to easily accept thermocouples commonly used with the Industrial thermometers they replace.

Slip-Fit dial thermometers are available in stem lengths that generally match those used for Industrial thermometers. Stem lengths from 3.5" (89 mm) up to 12" (305 mm) are offered as
standard, with custom lengths up to 60" (152 cm) available on special order. Temperature ranges from a low of -100°F (-50°C) to an upper limit of 1000°F (5000°C) are available in either °F or °C scales. Accuracy is stated at 1% of full range. A re-calibration method is provided on all models, as is over-range protection of up to 50% of range without resulting in permanent damage to the instrument.

"Slip-Fit", dial thermometers are also available with another unique Palmer feature. The "Replaceable Element" option allows quick, cost-saving replacement of the thermometer's internal sensing element and dial face assembly while leaving the external case, fitting, and stem components in place. "Replaceable Element" models also allow thermometer
replacement or temperature range change in situ, reducing costly process down time.

Many "Slip-Fit" models are available from stock. Custom models are fabricated in the Asheville, NC factory.
