Ashcroft T2 High Performance Pressure Transducer
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 applications. 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 temperature effects but also nonlinearity, hysteresis and non-repeatability.

Technical Specifications
PERFORMANCE SPECIFICATIONS
Ref. Temperature, 21°C ±1°C (70°F, ±2°F)
Accuracy:
Static Accuracy Class: ±0.25% of span (BFSL
Method) including non-linearity, hysteresis, non-repeatability
at reference temperature
Temperature Effect:
–20°C to 85ºC <±1% of Span – Total Error Band
–40°C to –20ºC <±1.5% of Span – Total Error Band
–85°C to 125ºC <±1.5% of Span – Total Error Band
Total Error Band includes the combined effects of
non-linearity (Terminal Point Method), hysteresis,
non-repeatability, temperature and zero offset and
span setting errors. For higher performance availability
