Hydac Electronic Pressure Transmitter HDA 4700 for Applications with Higher Level Functional Safety
Electronic pressure transmitter HDA 4700 for applications with higher level functional safety and outstanding performance in terms of temperature effect and EMC
Hydac Electronic Pressure Transmitter HDA 4700 for Applications with Higher Level Functional Safety
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).
It is also possible to use them in "SIL 2" systems (according to EN 61508).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 higher system.
The main areas of application are as sensor elements in mobile, safety-oriented 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
- Very compact design
- PL d, Cat. 3 certification
