INTRODUCTION TxMini-M12-MP Transmitter is a two-wire 4-20 mA type temperature transmitter powered by the current loop. You can use the SigNow software or app to configure it. To do this, simply connect the TxConfig-M12 Configuration Interface to the computer or smartphone being used. To configure it, the transmitter does not need to be powered.
SPECIFICATIONS FEATURES TXMINI-M12-MP Sensor input Pt100: 3-wire type, 0.8 mA excitation, α = 0.00384, according to NBR 13773. IEC 60751 (ITS-90). < 2.5 s. Time between energizing and stabilizing the measurement Accuracy is only guaranteed after 15 minutes. Environment: 25 °C (77 °F) •...
MECHANICAL INSTALLATION TxMini-M12-MP Transmitter is suitable for installation in pipes and in places with limited space. Vibrations, excessive humidity and temperature, electromagnetic interference, high voltage, and other interference can permanently damage the transmitter and cause errors in the measured value.
For correct compensation of the RTD cable resistances, they must be equal at all terminals and must not exceed 25 Ω per cable. To guarantee these conditions, it is recommended to use 3 or 4-wire cable of the same length and gauge (the cable is not supplied). NOVUS AUTOMATION 7/14...
