Transmissor de Pressão Eletrônico HDA 4700 Para aplicações com Segurança Funcional Maior

Description:

This version of the pressure transmitter series HDA 4700 has been specially developed for use in safety circuits / safety functions as part of the functional safety of machinery and equipment up to PL d – Cat 3 (in accordance with ISO 13849). The pressure transmitters are designed with two channels.

Each channel consists of a sensor element and evaluation electronics. As a result, the pressure transmitter develops two separate and independent output signals in proportion to the pressure.

The safety function is tested by evaluating and comparing the two analogue output signals in a higherlevel system. The main areas of application are as sensor elements in mobile, safetyoriented systems such as load torque displays or load torque limitation in truck-mounted cranes or working platforms.

Special features:

  • Two-channel, redundant pressure measurement
  • Two separate, independent output signals
  • Accuracy ≤ ± 0.25 % FS typ.
  • Highly robust sensor cell
  • Outstanding performance in terms of temperature effect and EMC
  • Small, compact design
  • PL d, Cat. 3 certifi cation
