Multiple Sensor Assemblies

Multipoint

Temperature profiling is important whenever multiple points of measurement are required over a broad measuring range. Multiple Sensor Assemblies or Multipoints as they are commonly referred to can be designed with using either thermocouples or RTDs and in some cases both. As illustrated above, secondary seals can be supplied for even greater safety assurance. These seals prevent process fluids or gasses from escaping in the event of a process upset. In critical applications component testing is recommended. Dye penetrated, X-ray, and hydrostatic testing are standard available tests.


In order to be effective these assemblies must be able to provide temperature point location with a tolerance of plus or minus .25 inches and comparable sensor accuracy throughout the entire measuring range. Our unique cross calibration method and positive point identification assures like sensor accuracy and accurate and safe performance.


2020
Sensors are installed into guide tubes which are terminated at the hot end into heat transfer blocks. These blocks are welded into the wall of the protection tube at the required points along the well. This facilitates faster response time, improved accuracy and positive point identification. Individual sensors can be removed while the unit is operating and without disrupting the process. This design lends itself to insertion in a secondary seal construction.


2030
This design maintains positive sensor contact to the inside wall of the protection tube for improved accuracy and response time. The sensors can be installed as a bundle with a support strip or individually. Sensors can be individually replaced.


2040
Several sensors are accurately positioned in a stainless steel tube and each sensor is transitioned to flexible leads. This construction does not require a protection tube.


2050
Each sensor is inserted into a guide tube and is individually spring loaded to provide good metal to metal contact with the measuring location. Sensors are easily removed without process shutdown.
