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.

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.

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.

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.

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.
