Application

Hydraulic & Pneumatic Control Systems

In modern industrial machinery, hydraulic and pneumatic systems serve as the core power and actuation source. The PT981 ensures stable, real-time pressure feedback for system safety, efficiency, and precise motion control.

Steel & Aluminum Rolling Mills

Rolling mills represent one of the harshest environments for industrial sensors-characterized by high shock, vibration, coolant exposure, and extreme mechanical stress. The PT981 is purpose-built to survive and perform under these conditions.

Machinery Operating Condition Monitoring

Rotating and reciprocating machinery in industrial plants demand continuous pressure monitoring to prevent unplanned downtime and catastrophic failures. The transmitter's rugged construction and 1000g shock tolerance make it ideal for these mission-critical applications.

Environmental Monitoring & Water Treatment

Beyond traditional industrial applications, the PT981pressure transmitter delivers drift-free, maintenance-friendly pressure measurement for environmental infrastructure and process water systems.
