APPLICATIONS

An affordable digitally compensated
instrument for general industrial
applications.

• Process Automation

• Compressor Control

• Hydraulic Systems

• Engine Monitoring

• Pump Control

• Pneumatics

• Refrigeration Equipment

• Presses

• Machine Tools

• Other General Industrial Applications

FEATURES

• 0.25% accuracy class

• Ranges 30 psi through 20,000 psi

• –40 to +125°C temperature capability

• All welded pressure construction

• Proven polysilicon thin film sensor

• Precision ASIC based electronics

• High EMI/RFI immunity rating

• Highly configurable

• Voltage and current outputs

• Choice of electrical connections

The T2 employs a polysilicon thin film sensor with
a proven long term stability. The sensor is electron
beam welded to a stainless steel pressure fitting
to ensure high overpressure ratings and integrity
in high shock, vibration and pressure cycling appli

­cations. Through the use of a high performance
ASIC and modern digital compensation techniques
the T2 provides extraordinary performance over
temperature. The graph that follows depicts the
performance over temperature on a Total Error Band
basis – the Total Error Band includes not only tem

­perature effects but also non-linearity, hysteresis
and non-repeatability.
