DESCRIPTION
The TD1200 Series digital/configurable (an industry first) industrial absolute pressure transducer features stability and accuracy over a wide temperature range at lower cost than competitive units typically not found in older analog designs yet is plug and play with most lower grade competitive units.

With its proprietary digital/ASIC technology, the TD1200 Series features field proven redundant sensing elements without the need for solder in resistors or trim pots that can drift over time. This provides years of excellent performance and reliability even in the harshest/demanding applications. This combined with optional 4x over pressure and the optional integrated temperature or pressure digital switch feature, makes the TD1200 Series truly an industry first and second to none.

For extreme applications where power washers are used for wash down, the TD1200 Series optional IP69K seal, another industry first, makes it ideal no matter what the environment.

With its flexible low power design and lower manufacturing costs, the TD1200 Series offers outstanding value and makes it ideal for custom wireless applications.

  Reverse Polarity Protection	Yes
  Zero and Span Offset Tolerance	1%
  Maintenance Mode	The maintenance mode digital output indicates 1/2 bridge failure and can be selected instead of pressure or temp set point with the designation“M”.
  Set Point for Pressure or Temp	For pressure, this is done by selecting a percentage of your transducer’s full range and this will be the set point (40% of a 1000 psi range will have the set point at 400psi)“P40”. For temperature, select your set point in degrees C such as 40°C (104°F) and this will be the set point “T40”. When set point is reached and becomes active there is a digital output on pin 4.
