Hermetically Sealed Thermocouples
Hermetically sealed thermocouples enclose the measuring junction in a moisture-tight seal so it can operate in wet, humid and washdown environments that would ruin an exposed sensor. At IOThrifty, our hermetically sealed thermocouples are built to keep moisture, condensation and contaminants out of the junction, giving you accurate, reliable readings in the conditions where ordinary wire thermocouples fail.
Why Use Hermetically Sealed Thermocouples
An exposed or lightly insulated junction can drift or fail when water, steam or humidity reaches the wires. A hermetic seal closes that path, protecting the junction against moisture ingress and the corrosion and shunting errors it causes. That makes hermetically sealed thermocouples the right choice for washdown areas, humid and condensing environments, immersion in non-pressurized liquids and any process where the sensor will get wet.
What Our Hermetically Sealed Thermocouples Offer
IOThrifty’s hermetically sealed thermocouples balance moisture protection, accuracy and durability. The sealed junction and insulated leads are built to stand up to humidity and repeated washdown, while standard connector and stripped-lead terminations make it simple to wire into meters, controllers, data loggers and PLCs.
Applications
Hermetically sealed thermocouples are used wherever moisture would compromise an unsealed sensor. Common uses include washdown and sanitary environments in food and beverage processing, humid and condensing spaces such as chambers and refrigeration, immersion checks in non-pressurized liquids, laboratory and pharmaceutical monitoring, and general process measurement where the sensor is exposed to water or steam.
