A Variety Of RTD Probe Types Available

By Gwen Lowe


In most industries and laboratories, RTDs are the most commonly used devices when measuring temperatures. These devices are installed with a resistor for measuring temperature and resistance variance and a core made of ceramics or glasses. In order to make these devices durable, they are secured under a RTD probe. These probes come in a variety of options for use in different applications.

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.

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.

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.

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.
