Frequently Asked Questions (FAQ)
Q: Can the sensor be used in high-temperature
environments?
A: It is not recommended to place the sensor directly under
high-temperature environments as it may affect its performance.
Q: How should I handle the sensor to ensure its longevity?
A: Avoid pulling the sensor lead wire, dropping or hitting the
sensor violently. Additionally, do not expose the transmitter to
steam, water mist, water curtain, or condensation for extended
periods.
