Plug and play conductivity meter with PLC interface

Datastick Conductivity Meter

Product Options

Overview

The DataStick with conductivity sensor head is able to yield highly accurate 24-bit conductivity data. Interactive communication with a host computer or display interface is possible via a wide array of connectivity protocols, including Modbus RTU, DeviceNet, Profibus, USB, CANopen and Ethernet. Connection to any computer can enable data display, calibration and customisation of the sensor. Connection to a PLC (Programmable Logic Controller) provides seamless integration with industrial control systems.

The sensor has a built-in pre-amplifier, universal engineering units conversion and universal signal conditioning electronics. It's built in electronics are completely encapsulated and O-ring sealed for protection from moisture and humidity. The DataStick Sensor System has exceptional mechanical strength and chemical resistance. Communication adapters and interchangeable pre-calibrated sensor heads can be fitted to the DataStick without the need to power down the system.
