Emerson TE1240 Temperature Transmitter 30 vdc 100 ohm Sensors Switches

More information:
The 1240 is a high performance temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration. It is intended for cost sensitive applications where excellent performance and long-term stability are required.

When using the 1240 with a fixed voltage reference and current set resistor as shown in the application schematic, a span of 50mV and 1% interchangeability can be achieved. Integral temperature compensation is provided over a range of -20°C to +85°C using laser-trimmed resistors. Absolute, differential and gage pressure ranges from 0-15 to 0-100 psi are available. Multiple lead and tube configurations are available for different applications.

Notes

•  Refer to application schematic.
•  Best fit straight line. Non Linearity for 2 PSI is ±0.2% 5 PSI is ± 0.50%.
•  Maximum temperature error between -20°C and +85°C with respect to 25°C.
•  Short term stability over 7 days with constant current and temperature.
•  Long term stability over a one year period with constant current and temperature.
•  For a zero-to-full scale pressure step change.
•  2X maximum for 100 psi device.
•  For pressure ranges below 15psi, compensated temperature range is 0oC to 50oC and thermal error of offet is ±1.25%.
