CASHCROFT Trust the shield.® Model T2 Pressure Transducer APPLICATIONS M12 Connection 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 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. 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, nonrepeatability at reference temperature Temperature Effect: -20°C to 85°C <±1% of Span - Total Error Band -40°C to -20°C <±1.5% of Span - Total Error Band -85°C to 125°C <±1.5% of Span - Total Error Band Total Error Band includes the combined effects of non-linearity (Terminal Point Method), hysteresis, non-repeatability, temperatureand zero offset and span setting errors. For higher performance availability consult factory Stability: Less than ±0.25% span/year Durability: Tested to 50 million cycles ENVIRONMENTAL SPECIFICATIONS Temperature: Compensated -40 to 125°C (-40 to 257°F) Humidity: 0 to 100% R.H., no effect Select from over 25 pressure ranges starting at 30 psi and running through 20,000 psi. Compound (vacuum & pressure) ranges are also available, see below. Overpressure (F.S.): Proof Burst Vibration: Random vibration (20 g) over temperature range (-40° to 125°C). Exceeds typical MlL. STD. requirements Shock: 100gs, 6 ms Drop Test: Withstands 1 meter on concrete 3 axis Response Time: Less than 1 msec Warm-up Time: Less than 500 msec typical Position Effect: Less than ±0.01% span, typical ELECTRICAL SPECIFICATIONS Output Signals Available: TOTAL ERROR BAND (TEB) Error limits of all points (0-100% of range) Ambient Temperature (C) □ Pos Error Limit Voltage Output Excitation Ratiometric Output 0.5-4.5 Vdc, 3 wire Current Output 4-20mA, 2 wire 9-36 Vdc Reverse Polarity & Miswired Protected: Yes Insulation Breakdown Voltage: 100 Vac Insulation Resistance: Greater than 100 megohms at 100 Vdc CE Compliance: Per EN 61326: 1997+ A1: 1998 + A2: 2001, Annex A (Heavy Industrial) All specifications are subject to change without notice.
