Sensorex TX2000 pH/mV Transmitter and CX2000 Conductivity/Resistivity Transmitter

Sensorex’s TX2000 pH/mV Transmitter and CX2000 Conductivity/Resistivity Transmitter monitor changes in process fluids for more accurate control in a wide range of water, chemical, electronics, food production, environmental and wastewater processing applications.

Both transmitters include Multi-Cal calibration with automatic buffer recognition, two assignable isolated analog (4-20 mA) current outputs, two alarm/control relays with an additional wash feature and a universal 100-240 VAC power supply. CE certified, the compact NEMA 4X/IP65 enclosures can be wall mounted, installed in a panel or pipe/handrail mounted.

The TX2000 has a pH measurement range of -2.00 to 16.00 pH and an oxidation reduction potential (ORP) measurement range of -1999 to 1999 mV. The CX2000 has a conductivity measurement range of 0.000 µS/cm to 200.0 mS/cm and a resistivity measurement range of 0.00 to 20.00 MΩ cm. Both are compatible with a number of probes and sensors to fit most application requirements.

An optional RS model offers additional features including data display charts and trend graphics, a real-time clock with logbook function and user-defined, five-point calibration with displayed calibration curve. The RS models are also equipped with one analog output and serial RS485 interface for Modbus RTU or ASCII communications, easily interfacing to existing plant SCADA or DCS control systems.

Both units have a large backlit display with easy-to-navigate text and graphic illustrations. A password protection option prevents unauthorised tampering. With a temperature span of -30 to 130°C, the transmitters are claimed to ensure accuracy even in challenging process environments.
