The high quality and reliable Rosemount 565/566 Multiple Spot Temperature Sensor (MST) measures temperature with a number of Pt-100 spot elements placed at different heights to provide a tank temperature profile and an average temperature. Rosemount 566 is used for cryogenic applications.
Only the fully immersed elements are used to determine product temperature.
The spot elements are placed in a flexible gas tight protection tube made from convoluted stainless steel.
A flange can be attached to a top fitting and the tube can be anchored to the bottom.
Rosemount 565/566 is easy to install, even if the tank is in service. In pressurized tanks the MST can be installed in a closed thermowell so that it can be removed for service or inspection while the tank is in operation.
For LPG tanks, single spot temperature sensors in thermowells are used.
Rosemount 565/566 is connected to the 2240S Temperature Transmitter.
A water level sensor or a junction box can be integrated to the multiple spot temperature sensor.
