Page 3: Introduction
Introduction Applications Resistance temperature sensors are used to monitor the heat of hydration in mass concrete. Operation The temperature sensor consists of a stainless steel body, an RTD or thermistor inside the body, and a signal cable. The resistance of the RTD or thermistor varies with temperature. The readout unit or data logger converts the resistance reading to degrees C Resistance Temperature Sensor, 2004/11/18... -
Page 4: Installation Suggestions
Installation Suggestions • Sensor When a temperature sensor is mounted in a particularly vulnerable position, consider spraying the area with marker paint, covering the gauge with a protective wire mesh, or placing some non-structural steel to protect the gauge. Damage is most likely to occur when the reinforcing gauge is lifted and then placed and also when the tremie pipe places the cement. -

Page 6: Diagnostics
Diagnostics No Reading Set your handheld multimeter to a low-ohm range (5k ohm). • Measure the resistance between the RTD/Thermistor wires (blue and white). Thermistors should read about 3000 ohms. RTDs should read about 2000 ohms. If the reading is very high or infinite, the tempera- ture device is damaged (or the cable is severed).
