Commonly deployed in oil refining and chemical processing plants where measurement integrity is critical. The TMR architecture enables continued operation even after single-point failures – a client in Texas reported 99.999% uptime during 18 months of continuous service in a hydrocracker unit. Its differential input configuration reduces noise susceptibility in high-EMI environments.
We maintain 14 units in active inventory across our global network, with typical delivery within 72 hours ex-Hong Kong warehouse. Our engineers can provide compatibility verification with existing Triconex system configurations and assist with calibration requirements.
