Pipe Immersion Temperature Sensors

Pipe immersion sensors are a popular and efficient solution for measuring gas and liquid temperatures within piping and process systems. Baelz North America offers a variety of sensor shaft lengths (100-800 mm) suitable for a broad range of commercial and industrial applications.

Pipe immersion temperature sensors are available in screw-in or weld-in mounting options and contain a shaft that remains in contact with the process flow. This shaft continuously transmits temperature to the platinum resistance measuring element, providing real-time process flow temperatures.

At Baelz North America, our pipe immersion temperature sensors accurately measure temperatures in liquid or gaseous process systems. When the temperature is known, the sensor communicates data to the controller, as well as the location where the temperature was measured in the process. For example, a temperature reading may look like this: 150° F at 100 feet.

The sensors are used along with controllers that have suitable 1x PT100 or 2 x PT100 inputs for measuring elements. They can be used in alignment with the following controllers:

  • Baelz 6490
  • Baelz 6590
  • Baelz 6164
  • Baelz 6200

 

Available shaft lengths for the sensors include:

  • 100 mm
  • 200 mm
  • 300 mm
  • 400 mm
  • 600 mm
  • 800 mm

Mounting and Installation

Installation and mounting best practices should be followed, which will ensure a quick response behavior. The sensor should be mounted so that the fluid covers the total length of the shaft whenever possible.

Protection Wells

Immersion sensors are inserted into a protective well. This well provides a tight seal and maintains the pressure of the piping system. The length of the protection well depends on the length of the shaft. For liquid measurements, the minimum immersion depth should be the 5-10 times the diameter of the protection well. For gaseous fluids, the minimum depth is the 15-20 times the protection well diameter. The immersion depth should be less than the temperature-sensitive length of 35 mm.
We offer two types of protection wells for use with our sensors:

  • 251-S5: Stainless Steel Screw-In Protection Well (65mm, 145 mm, 245 mm, 345 mm, 545 mm ) Note: Optional compression fitting available. It requires compression fitting R ¼”.
  • 251-S6: Stainless Steel Weld-In Protection Well (Lengths: 145 mm, 245 mm, 345 mm, 545 mm)

Applications

These sensors are commonly used in industries such as:

  • Wood
  • Food
  • Marine
  • Automotive
  • Power
  • Chemical
  • Water and Wastewater
