RTD Probe Types Found On The Market

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.

Among the main types available is the spring-loaded probe. This option is made with a alumina lagging to reduce vibration and improve the rates at which heat can move. Some devices are also covered with a sheath to guarantee high standards of safety. With these apparatus, people can easily replace them when there is need or even connect them to the wiring junction box with ease.

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.

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.

Other types of probes available in the market are the bolt-on-ring probes. Normally, these are devices are mounted with brass rings, metal sheathing and over-braids. Different options vary in size hence when choosing an option to suit your needs, you should ensure the screws and bolts have 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.

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.
