Intelligent Transmitters for pH/ORP and Conductivity

Sensorex’s (USA) TX2000 pH/mV Transmitter and CX2000Conductivity/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 analogue (0/4-20mA) current outputs, two alarm/control relays with an additional wash feature, and a universal 100-240VAC power supply. CE certified, the compact NEMA 4X/IP65 enclosures can be wall mounted, installed in a panel or conveniently pipe/handrail mounted.

The TX2000 has a pH measurement range of -2.00 to 16.00pH and an oxidation reduction potential (ORP) measurement range of -1999mV to 1999mV. The CX2000 has a conductivity measurement range of 0.000 uS/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 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 customer defined five-point calibration with displayed calibration curve. The RS models are also equipped with one analogue output and serial RS-485 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 °C to 130 ° C Sensorex transmitters ensure accuracy in even the most challenging process environments.
