Critical Force Measurement with ZT-1 & ZT-4
The ZT tonnage load module is designed for critical force measurement applications where accuracy, extreme stability, and dependable noise rejection is essential. It is equipped with an LED bar-graph voltmeter for easy setup and diagnostic. The ZT is DIN rail mountable and is designed to interface with a PLC analog card and to display output through a human machine interface (HMI).
The ZT module is available in Single-Channel (the ZT-1 as pictured above) and in Four-Channels (the ZT-4 as pictured to the right).
