Sensorex’s TX2000 pH/ORP series transmitters’ advanced technology delivers critical analytical information from process sensors to water treatment plant operators. Designed for use with Sensorex’s easy-to-clean flat surface technology sensors, the user-friendly TX2000 integrates easily with plant control systems.

Influent process monitoring can alert water treatment plant operators to contaminated raw sewage entering the plant, allowing it to be diverted and further treated to avoid process upsets.

In plants using biological treatments, ORP measurement is frequently used for process control. Full featured with alarm/control relays and current outputs (4-20mA), the TX2000 transmitter interfaces to plant SCADA or DCS control systems, keeping operators apprised of changing process conditions.

The transmitter features easy-to-navigate text and graphic illustrations in a large display, backlit for operation in low light conditions. Supplied in a compact NEMA 4X/IP65 enclosure, units can be wall mounted, installed in a panel, or conveniently pipe/handrail mounted.

An optional TX2000RS model offers additional features including data display charts and trend graphics, a real-time clock with logbook function, and customer defined 5-point calibration with displayed calibration curve. The RS model is also equipped with one analogue output and serial RS-485 interface for Modbus RTU or ASCII communications, for digital interface to existing plant SCADA or DCS control systems.

Both models are CE certified and include Multi-Cal calibration with automatic buffer recognition and universal 100-240VAC power supply. 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.
