Some Common RTD Probe Types

By Gwen Lowe


Resistance temperature detectors are essential for various applications especially in industries and laboratories where accurate temperature measurements are required. This apparatus has a glass or ceramic core and a resistor, which changes its resistance value as temperature changes. The materials used to make this device are very delicate hence need to be secured under a RTD probe. There are various types of probes available that are used for various types of resistance temperature detectors.

One of the main types of probes is the spring-loaded that is lagged to guarantee high levels of protection to the apparatus. The device is also lagged with an alumina powder that allows for proper heat transfer and reduction of vibration. The good thing with these apparatus is that people can change it whenever they want and attach it easily to the wiring junction box.

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.

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.

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.

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.

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.
