Some Common RTD Probe Types

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.

Other popular types of probes come with an attached plug. This plug allows for quick and easy wiring connections. The device is insulated with an alumina powder, which acts as a preventive mechanism to protect the probe from all types of environmental damages. This insulation also acts to better the standards of heat transfer and vibration dampening with the system.

The built-in head connection probes come with cast aluminum screw cover head, insulated alumina powder and a well-sealed sheath. Some also have a ceramic terminal base, which are attached to stainless steel screws and brass terminals. The alumina lagging is designed to provide suitable protection to the device.

Other popular devices are the wall-mount room temperature types. The main types of these devices come with internal terminal strips, metal wall mounted sub-plates and plastic ventilated covers. Most of them have high standards of versatility and people can easily mount them in the vertical and horizontal position. In order to improve their performance, the plastic ventilated coat in most of the devices is covered with a sheathed coat.

Bolt-on-ring probes are other popular options. Numerous types of these types have their rings obtained from brass materials. Some would also have metallic over-braids and sheathing. The size of the screw or bolt to be used on these apparatus would depend on the diameter and size of the ring.

The adjustable spring immersions probes are also common. Most of the devices that are designed in this make come with a lead wire transition and adjustable spring to guarantee the provision of the variable immersion and metallic sheathing. Some have a pierced cap, which ensures people can easily and quickly connect it to their adapters.

People consider various factors whenever shopping among which is product type. The main reason for doing this is to ensure they can get the right product that suit their desires since different products would be created differently to be used for different purposes. When shopping for RTDs, you should also consider the type to go for since there are many types available that are used for different purposes. In order to get the best option, it is advisable you research the various types available to know their benefits and drawbacks.
