PCIe-Mini-DTMS
Multi-Sensor, High Accuracy Digital Temperature Measurement System
The PCIe-Mini-DTMS is a Mini PCI Express x1 module that can be used as a complete temperature monitor and control device. Its versatile input choices and multiple output capabilities satisfy an extensive range of application requirements. The DTMS measures a wide variety of sensors, and it digitally outputs the results with 0.1ºC accuracy and 0.001ºC resolution. It can measure temperature with standard 2- 3- or 4-wire RTDs, Thermistors and Diodes, and with virtually all standard or custom Thermocouples.
Measurement System capabilities
- Directly digitizes 2- 3- or 4-wire Thermocouples, RTDs, Thermistors and Diodes
- Automatic Thermocouple cold junction compensation
- Built-in standard and User-programmable coefficients for Thermocouples, RTDs and Thermistors
- Measures negative Thermocouple voltages
- Buffered inputs allow external protection
- Simultaneous 50Hz/60Hz rejection
- Includes 15ppm/ºC reference
- Integrated EEPROM stores channel configuration data and custom coefficients
- Interfaces directly to ground-referenced sensors without needing level shifters, negative supply voltages or external amplifiers
- All temperature input signals are buffered and simultaneously digitized with three high-accuracy 24-bit ΔΣ ADCs, driven by an internal 10ppm/ºC (max) reference.
Digital I/O capabilities
- Four digital I/O channels, with software programmable direction
- Two relays control up to 200mA (Sink)
- Two open collector output channels
- One output channel, 4-20mA
Applications
- Temperature monitor and system control
- Direct Thermocouple, RTD and Thermistor measurements
- Custom sensor applications
