RTD Probe Types Found On The Market

By Gwen Lowe


In most industries and laboratories, RTDs are the most commonly used devices when measuring temperatures. These devices are installed with a resistor for measuring temperature and resistance variance and a core made of ceramics or glasses. In order to make these devices durable, they are secured under a RTD probe. These probes come in a variety of options for use in different applications.

The spring-loaded with hex nipple probes come with properly aligned sheath that protects the device against harsh environments. It also has a sheathed alumina powder insulation, which guarantees proper heat transfer and vibration dampening. These devices are designed in such a way that you can easily connect it to the wiring junction box besides being able to replace the existing probes any time a need arises.

Attached-in plug probes are also popular. Most of these gadgets are lagged with alumina powders to guarantee high standards of safety and plug-in mechanisms to make the wiring process easier. These devices are also lagged to enhance the rates at which heat can move and reduce the impacts of vibration.

Another common option is the built-in head connection probe. These types have an alumina lagging, sealed sheath, aluminum screw-cover head and ceramic terminal base. The ceramic terminal base is usually fastened with a brass terminal and stainless steel screws. The main purpose of insulating these devices is to secure the device from various harsh conditions.

Wall-mount room temperature probes are also common. These come with a metal wall mounting sub-plate, plastic ventilated cover and internal terminal strips that are essential for wiring connections. These apparatus are very versatile which ensures you can mount them both vertically and horizontally to the surface. In some designs, the plastic ventilated cover is coated with a sheathed coat to provide better standards of protection.

The bolt on ring is another kind of probe available. The rings installed in these apparatus are made from brass materials, lagged with sheaths and metallic over braids. If you decide to go for this option, you should make sure the choice you have chosen has a bolt or screw with the same size as the diameter of the ring.

Manufacturers also make the adjustable spring-immersion probe types. When designing these types of probes, manufacturers mostly fit them with an adjustable spring and lead wire transition. The purpose of the adjustable spring is to allow for sheathing and improve the variance in immersion. The pierced cap is also another common element in these devices that aids and enhances their connection to the adapter.

Whenever shopping, most people not only base their search on quality of certain products but also the type of product. This is because all products are not the same and cannot be used for the same application. It is also the same when shopping for resistance temperature detector probes as not all probes are the same and can be used for the same application. When looking for the best probes to suit your needs, it would be essential first you know the different types available and their uses in order to decide on which to choose.
