The compact 2-wire transmitter – the link to the PLC and DULCOMETER®. The 2-wire transmitter DMTa converts the following sensor signals into an interference-insensitive 4-20 mA analogue signal: pH, ORP, temperature, chlorine and conductivity. It is fed via the 2-wire analogue input of a PLC or via a 2-wire analogue input of a ProMinent controller. The 4-20 mA analogue current proportional to the measured value is transmitted via the same two lines. The DMTa offers an on-site calibration option of the sensor and galvanic separation between the sensor input and measured value output. Your benefits Flexibility in the choice of measured variable with pH, ORP and temperature Excellent operational safety, thanks to sensor monitoring (pH) Galvanic isolation between the sensor and supply Always the optimum measured value resolution by auto-ranging with conductivity measurement Safety through sensor monitoring of pH for glass breakage and line breakage Various installation options: wall-mounted, installation on an upright or in a control cabinet
