Surge voltage test report of cyb230 universal pressure transmitter

Published on: August 3, 2020 by Zetian Technology

Surge voltage test purpose of cyb230 universal pressure transmitter

Cyb230 pressure transmitter is a universal pressure measuring device which is widely used in various environments Cyb230 pressure transmitter Whether the power supply can withstand 50VDC / 100ms surge voltage. It provides the basis for the reliability of cyb230 pressure transmitter. The typical electrical connection and physical object of pressure transmitter are shown in the following figure:

Surge voltage test basis and method of cyb230 universal pressure transmitter

When the external supply voltage is higher than the safety voltage of the circuit, the transient suppressor will be broken down and discharged. The discharge power is 600W and the discharge response time is 1x10-12s. At the same time, the supply voltage of the circuit is clamped to the safety voltage of the circuit, so as to protect the internal circuit from external surge voltage damage.

Experiment method: under normal temperature and high temperature, apply 50VDC / 1s fixed voltage to the power input terminals of two transmitters for three times to check whether the transmitter is damaged (high temperature test is conducted at high temperature, and record the normal temperature zero point after the experiment).

Surge voltage test data of cyb230 universal pressure transmitter

Product number Transmitter zero output (unit: V)
Before experiment (25 ℃) Room temperature experiment (25 ℃) Room temperature (25 ℃) after 125 ℃ experiment
C9B009 one point one zero six one point one zero five one point one zero nine
C9B010 one point one three six one point one three five one point one three five

From the surge voltage test data of cyb230 universal pressure transmitter, it can be seen that under normal temperature and high temperature, when the external short-term high voltage is applied to both ends of the power supply, the output of the transmitter is normal, and the short-term high voltage will not affect the circuit.
