  • 60 in cable provides flexible panel-mount placement

Product Identity

The Value Brand 12U657 is an analog panel-mount thermometer built for industrial and mechanical environments where a local temperature reading is required without external power. It suits technicians and plant operators who need a direct, vapour-actuated indication across a 30 to 300 degree F range.

Sustained Operation

Because the instrument is vapour-actuated, the pointer responds continuously to the bulb temperature without electronic drift or battery depletion. The copper probe and aluminium housing withstand prolonged exposure to the full 300 degree F upper limit, maintaining readability through the glass lens during extended duty cycles.

Interface Limits

The 1/2 in MNPT process connection and 60 in capillary cable fix the installation geometry; the probe diameter of .4 in and 2 in insertion length determine the minimum fitting size and the thermal response time. The 4.5 in dial diameter sets the maximum reading distance, so the unit cannot serve applications that require remote transmission or data logging.

Questions about this item

How much heat does the analog panel-mount thermometer generate when it runs continuously all day?

The thermometer is a passive vapor-actuated instrument with no power supply, so it produces no measurable heat during continuous operation.

What mounting hardware or panel cutout must I already have to install the 4.5 in dial with its 1/2 in MNPT probe fitting?

You need a panel opening to suit the 4.5 in dial and a 1/2 in MNPT threaded port for the .4 in diameter copper probe.

Will the 60 in capillary cable reach an existing gauge cluster if the probe stays in the current 2 in immersion depth?

The 60 in cable provides a fixed 5 ft separation between the probe tip and the dial, so the gauge cluster must be within that distance.
