This type of detector is designed to be used in a situation where the user wants to measure the distributed temperature of a reactor or a container. It can measure horizontally distributed temperature and also can measure the temperature in each depth of the container or the reactor. It is also designed to consider the size of nozzle, installation space and requirement, and convenience of repairing and replacing. Wise Control Inc. can manufacture any types of multi point temperature sensors, and upon request of the customer, we can employ the requested material of protection tube, the material of sheath, size, measuring points, and the method of attaching the senor. Espscially, we can provide the temperature sensors without protection tube in a high pressure line by employing our own safety measures. The temperature sensors for junction box to connect the terminal can be manufactured in explosion proof type.
