A Variety Of RTD Probe Types Available

By Gwen Lowe


RTDs are among the most commonly used devices for measuring temperatures in laboratories and industries. The common types of these devices are mounted with a resistor for measuring temperature and resistance variation in addition to a core obtained from glass or ceramic materials. Manufacturers also design these devices with probes, which protect the devices from damages. When you decide to purchase an RTD probe, you would find various options to choose from.

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.

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.

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.

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.
