Product Description

ConST 326 Dual - mode HART Communication Intelligent Multi - Function Process Calibrator

The ConST 326 Dual - mode HART Communication Intelligent Multi - Function Process Calibrator is a cutting - edge instrument designed to meet the diverse calibration needs in industrial processes. Engineered with precision and versatility in mind, it has become an essential tool for professionals in various industries.

Enhanced Accuracy

 Versatile Signal Handling

 Sweep Functions for Thorough Testing

The ConST 326 stands out with its dual - mode HART communication capability. It can operate in both primary and secondary HART communication modes. In the primary mode, it acts as a master device, enabling seamless communication with HART - enabled field instruments such as transmitters, valves, and sensors. 

In the secondary mode, the ConST 326 functions as a slave device. This feature is particularly useful when it needs to communicate with a host system or a control room. It can receive commands from the host and send back calibrated data and diagnostic information. 

This calibrator is a true multi - tasker when it comes to signal handling. It can source and measure a wide range of signals. For electrical signals, it can generate and measure DC voltage up to 30 V with high accuracy, and DC current up to 24 mA.
