Ưu điểm kỹ thuật quan trọng
-
Straightforward Sensor Support: The TMT31 is available in two dedicated versions to suit your primary sensor needs: one optimized for Pt100 and Pt1000 RTD sensors, and another for all common thermocouple (TC) types. This specialization ensures stable signal conversion for the most widely used industrial temperature probes.
-
Fast Push-In Terminal Technology: To significantly reduce labor time during setup and maintenance, the transmitter features push-in terminals. This allows for rapid, tool-free wiring that is more resistant to vibration than traditional screw terminals, ensuring a secure electrical connection over the life of the instrument.
-
Accurate Sensor-Transmitter Matching: By utilizing the Callendar-van Dusen (CvD) coefficients of a specific RTD sensor, the TMT31 can be matched perfectly to the probe. This calibration technique eliminates the standard interchangeability error of the sensor, providing much higher total measuring point accuracy.
-
Standardized Diagnostics: In alignment with NAMUR NE 107, the TMT31 provides clear diagnostic status information. It monitors the health of both the internal hardware and the connected sensor (detecting wire breaks or short circuits), allowing for faster troubleshooting and improved plant uptime.
-
Zone 2 / Div. 2 Safety: The transmitter is approved for use in hazardous areas classified as Zone 2 (Ex ec) or Division 2. This makes it a safe and compliant choice for a vast range of chemical, energy, and general process environments.
-
Versatile Form Factors: The device is designed for maximum installation flexibility. It fits perfectly into standard DIN Form B terminal heads for field thermometers or can be ordered as a DIN rail module for centralized control cabinet integration.
