resistive temperature sensor

In actual on-site monitoring, resistive temperature sensors (RTDs) often replace thermocouples because of their excellent long-term stability and interchangeability. The RTDs provided by Kingmach are usually based on PT100 or PT1000 temperature sensing elements, encapsulated in 316L stainless steel protective tubes, and sealed with epoxy resin or heat shrink tubing to ensure reliable operation in moisture-saturated boreholes or inside concrete. The measurement range generally covers -50℃ to 150℃, and it can be customized if a wider range is required. In terms of accuracy, we usually offer grade A or grade B to match different budgets and performance needs. The most common uses of this type of sensor in the hands of our customers include: seepage temperature monitoring in dams and embankments - determining the location of leaks through temperature gradients; temperature distribution measurement in frozen soil and roadbeds; and temperature control during large-volume concrete pouring. Because reading the temperature requires a secondary instrument, we can also provide a transmitter with a 4-20mA or Modbus RTU output to allow the data to be uploaded directly to your automation system. For projects with specific installation requirements, almost every parameter can be adjusted: the probe length ranges from a few centimeters to several meters, the diameter is from 3mm to 8mm, the leads can be made of PVC, PTFE or silicone, and the connectors can be bare wires, junction boxes or M12 aviation plugs. Ice water bath calibration will be done before delivery and test records will be attached. Our customer network covers more than 20 countries, and local partners can provide timely on-site support. If the standard products don't meet your idea, you may as well send us your requirements - we can deliver samples within two weeks for most customized solutions.
