Pyxis Lab ST-723 Inline High Temperature/Pressure Conductivity Sensor

Overview

The ST-723 is a high temperature boiler-water conductivity sensor that is ideal for applications measuring boiler water and other process water samples with an elevated temperature and pressure. The sensor is constructed with a Hastelloy 2-pole electrode head and PEEK type plastic with a 316L stainless steel body. Features include integrated cooling fins, allowing utilization on water samples as high as 200 ºC (392 ºF) and 300psi. The sensor has a built-in RTD for temperature measurement, allowing for sensor configuration with or without Automatic Temperature Compensation (ATC) and a user defined compensation coefficient. The ST-723 offers both 4-20mA & RS-485 Modbus outputs in an 8Pin format with Bluetooth access capability for wireless data trending, configuration and calibration using the MA-CR Bluetooth® adapter. Features Dual 4-20mA & RS-485 Outputs for Connection to ANY Controller, PLC, DCS Wireless Configuration & Calibration via MA-CR Bluetooth® Adapter and uPyxis app Rugged 316 Stainless Steel & PEEK Design Hastelloy 2-Pole Electrode Sensor Head
