All purpose economy
We have engineered our strap-on sensors to ensure long life and rapid response. The sensor is mounted using PC board technology to eliminate strain on the sensor leads, increasing reliability. This assembly is potted in heat transfer compound to provide rapid response and cushion the sensor from vibration. The eight foot PVC lead wire makes it convenient to connect to a nearby utility box.
Platinum RTD's are the most stable temperature sensors between -50 and 400C. They show almost no calibration drift with time. Their stability, wide temperature range and almost linear output make them the choice in demanding applications. Our standard RTD uses a 100 ohm platinum thin film element to DIN 43 760 (IEC 751) with a tolerance of +/- 0.3 deg C. We also supply thin film RTDS's with a tolerance of +/- 0.1 C in values of 100, 500 and 1000 ohms. Wire wound ceramic RTD's with accuracies as high as +/- 0.06 degrees Celsius are in stock for high precision applications.
NTC thermistors are the most sensitive sensors known to exist for temperature measurement from -50C to +150C. The temperature coefficient of thermistors can be as high as several percent per degree C. This means that lead resistance from installation of thermistors in remote locations has minimal effect on system accuracy. Since they are semiconductors they must not be exposed to temperatures above their operating limits or they can drift out of specified tolerance. Our standard thermistor has a 10K resistance at 25 deg C and a tolerance of +/-0.2C. On request other calibrations and accuracies available on order.
