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.

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.

Another popular device available is the wall-mount room temperature, which mostly comes with internal strips, plastic ventilated covers and metal sub-plates. With these apparatus, you can easily mount them both with the horizontal and vertical position. The plastic coating is enclosed with strong coating to improve its performance.

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.

There are various factors, which people should consider when purchasing certain items. One of the main factors is the type of the product to be purchased since not all products are the same. Therefore when purchasing probes, you should also make sure you determine which type to choose as there are various types available that can be used for different applications. To choose the best option, people are supposed to familiarize with the common types available and their advantages and drawbacks as this would be the best way to help them make a wise decision.
