Tempco Specialty Sensors
Tempco has a wider variety of specialty sensors that fit your application needs. These sensors include Precision Centigrade Temperature Sensors, 2000 Ohm RTD Sensors, Spring-Loaded Surface Contact Thermocouples, and Compound Mixer Thermocouples.
Precision Centigrade Temperature Sensors
This sensor probe utilizes a dual precision integrated-circuit temperature sensor, whose output voltage is linearly proportional to the Celsius temperature. This sensor does not require any external calibration or trimming to provide typical accuracies of ±1/4°C at room temperature or ±3/4°C over a full –55°C to 150°C temperature range. This sensor includes a Molex 4-pin connector.
Design Features:
- Calibrated directly in °C
- Linear +10.0mv/°C scale factor
- ±1/4°C accuracy (at 25°C)
- Rated to full -55°C to 150°C range
- Suitable for remote applications
- Operates from 4 to 30 volts
- Less than 60µa current drain
- Low self-heating, 0.08°C in still air
- Nonlinearity only ±1/4°C typical
- Low impedance output, 0.1Ω for 1ma load
2000 Ohm RTD Sensors
This sensor probe is a fast responding 2000 ohm RTD sensor used widely in the hvac, appliance and automotive industries.
Design Features:
- Protected in a 316 SS housing and supplied with 22 ga. Teflon® leads.
- 2000 ohm nominal resistance at 20°C
- Accurate to ±0.7°C at 20°C
- Near linear temperature sensitivity; provides 8Ω/°C sensitivity
- ±3% max. linearity (can be linearized to ±0.2%)
- Long term stability
- Interchangeable without sensor-to-sensor recalibration
- Operating temperature range of –40°C to +150°C
Spring-Loaded Surface Contact Thermocouples
