Industrial thermometers
The thermometers in this category are dial-type instruments used for continuous temperature display in heating equipment such as boilers and hot water cylinders, in tea machines, in cold rooms and display cases, and in machinery and process lines. Unlike domestic thermometers, they are permanently mounted on a device or pipe and provide reliable readings over extended periods.
Types of thermometers
- Immersion-pocket thermometers: Inserted into a pipe or tank via a sensing pocket; the immersion length is selected according to the measurement point.
- Panel-mount (rear-connection) thermometers: Mounted on equipment panels and casings.
- Gas-actuated (capillary) thermometers: A capillary tube runs between the sensor and the dial, enabling remote reading.
- Low-temperature thermometers: Models capable of measuring sub-zero temperatures; for refrigeration units and display cases.
- Contact (electrical) temperature gauges: Provide a contact signal at a set temperature to enable control or alarm functions.
Choosing the right thermometer
The measurement range must cover the lowest and highest temperatures of the application; the operating temperature should not be too close to the upper limit of the scale. The immersion length should be sufficient to ensure that the sensor extends adequately into the fluid. Dial diameter is determined by readability requirements and available mounting space. The connection type (bottom, rear, or capillary) must suit the installation location.
Installation and maintenance
The thermometer should be positioned at a point where it can sense the true temperature of the fluid, away from dead zones. Using an immersion pocket allows the thermometer to be removed without draining the system. If fogging appears on the dial glass, or if cracking or a stuck pointer is observed, the instrument should be replaced. On capillary models, the capillary tube must not be bent or crushed.
Frequently asked questions
What does immersion length mean?
It is the length of the thermometer's sensing element that extends into the fluid.
What range is suitable for a boiler?
Heating boilers typically use thermometers with a 0–120 °C range; select according to your boiler's operating temperature.
What does a contact thermometer do?
It provides an electrical contact at a set temperature to control a pump, fan, or alarm.
Which model for a cold room?
Low-temperature thermometers capable of displaying sub-zero values should be preferred.
Why is the thermometer reading incorrectly?
The sensor may not be making sufficient contact with the fluid, or the instrument may be damaged.
Can temperature and pressure be measured together?
Yes; thermo-manometers display both values on a single dial.
Does the thermometer pocket need to be purchased separately?
Some models come with a pocket included; others require a separate pocket. Check the contents description and immersion length in the product information.
