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.

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.

The attached-in plug probe is also common. The use of the plug is to ease wiring connections while the alumina powder insulation is used to secure the device from the impacts of various harsh environmental conditions. The alumina powder insulation is also essential for enhancing transfer of heat and reduction of vibration.

One other popular probe is the built-in head connection, which is mostly attached with a sealed sheath, alumina powder lagging and screw heads made of cast aluminum. Other common attachments in these devices are the brass terminals and stainless steel screws. The main reason for lagging these devices is to ensure the device is kept under the right standards of safety.

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.

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.

Another common option in the market is the adjustable spring immersion. These apparatus come with lead wire transitions and adjustable springs, which better the standards of metallic sheaths and the variations of the immersion. If you want a device that can be connected easily to its adapters, you should consider the one with a pierced cap.

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.
