MTL

Plug-in Signal Conditioners M-UNIT

2-WIRE STRAIN GAUGE TRANSMITTER

Functions & Features
• Used in conjunction with bridge type strain gauges utilized in load cells, pressure transducers, etc.
• Excitation in pulses enables use with strain gauges of the bridge resistance 350 Ω
• Non-isolated
• Zero adjustment range: 0 to 80 %, span adjustment range 100 to 20 %
• High-density mounting
Typical Applications
• Weighing system for tanks, hoppers, silos
• Weighing system using cranes
• Float level meter utilizing strain gauges
