Bedook Capacitive High Temperature Sensor
The Bedook Capacitive High Temperature Sensor is a remarkable device. Its probe, made of PTFE, can handle media temperatures up to 230°C. The sensor and amplifier are designed separately, allowing for easy probe fixation. It has an IP66 ingress protection, ensuring durability in harsh environments. With an operating voltage ranging from 18 – 30VDC for Sensor – I and 24VDC for Sensor – II, it is suitable for various power supply setups. The switching frequency is 10Hz for both, and the no – load current is ≤50mA.
