Web Sensor with PoE - remote thermometer hygrometer with Ethernet interface
Ambient temperature, relative humidity t-line Web sensor with Power over Ethernet feature. Remote alarm.
PoE Web Sensor with built-in relative humidity and temperature sensors. Can serve as a weather sensor.
High precision capacitive polymer sensor ensures excellent long-term calibration stability and ultimate accuracy. Dual-line LCD is an advantage. The power over Ethernet feature according to IEEE 802.3af is supported. Measured values are also converted to other humidity interpretations: dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy.
Processing and analysis of measured data:
online in COMET Cloud
COMET Database software
integration into 3-party systems

Wireless thermometer, hygrometer, Sigfox IoT
The device measures the temperature and humidity from the built-in internal sensor. It is characterized by a simple compact design with the possibility of installation directly into the measured space. The sensor can be used with a suitable sensor cap even in more demanding conditions.
The measured values are sent in an adjustable time interval (10 min to 24 h) by radio transmission in the Sigfox network to the COMET Cloud, from which the user can view them using a personal computer or mobile device.
The instrument can monitor up to 2 alarm limits of the measured variable. Exceeding these limits is indicated by sending an emergency message. COMET Cloud transmits this alarm message via e-mail to the selected user. The device is suitable for applications that tolerate the delay of information delivered by Sigfox (max. 10 min).
Highlights:
wireless transmission of measured values and alarm status
battery power with low battery indication (battery life 4 months to 7 years)
external power with optional accessories
remote setting of the device from COMET Cloud (maximum once a day)
IP65
traceable calibration certificate in accordance with EN ISO / IEC 17025

Zener Barrier ZbC2+
The Zener barrier ZbC2+ is a certified intrinsically safe interface. It is used to connect a certified intrinsically safe device located in a potentially explosive atmosphere (Hazardous area) to a non-certified device that is in a safe area.
The Zener barrier prevents the transfer of unacceptably high energy from the safe area into the hazardous area. The ZbC2+ Zener barrier contains two identical diode return barriers in a common housing and it is designed for DIN rail mounting in a safe area.
