Comet H3531P Compressed-Air Thermometer Hygrometer with Ethernet Interface and Relays
- High demand for on-line monitoring
- Uninterruptable records of different type of values
- The Ethernet net has direct connection to the internet
- High requirements could be done easily by Web Sensors and sensors with Ethernet output
- The devices can be protected against blackouts and data loss at the customer’s site
- Measuring temperature, relative humidity, CO2 concentration, atmospheric pressure, and the 4-20mA signal
Compressed-air ambient humidity, temperature Ethernet sensor with two relay outputs. T+RH probe from hard anodized duralumin for compressed air up to 25 bars with cable.
Sensor H3531P is designed for online monitoring of temperature, relative humidity of air without aggressive substances. Three binary inputs to detection of two-states signals are the advantage. Other devices are controlled by two relay outputs.
High precision capacitive polymer sensor ensures excellent long term calibration stability and ultimate accuracy. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio and specific enthalpy.
These days there is a high demand for on-line monitoring and uninterruptable records of different type of values. With very fast development of computer technologies, it is still easier and easier to connect different kind of monitoring devices directly to Ethernet lines, to the places where it was not possible before. If the Ethernet net has direct connection to the internet. This high requirements could be done easily by Web Sensors and sensors with Ethernet output which can ensure long term reliability, stable parameters and very easy installation and usage. The devices can be protected against blackouts and data loss at the customer’s site. Of course PoE supply is an option.
Continuous monitoring of critical parameters such as temperature and relative humidity can be very easily done by the help of Web Sensors. This production line consists of sensors for measuring temperature, relative humidity, CO2 concentration, atmospheric pressure, and the 4-20mA signal. Most sensors are equipped with an LCD display and can be easily incorporated into the existing network infrastructure.
The Web Sensors evaluate the measured values and in case of exceeding the alarm limits, the unit will send an email to a pre-set address, so this ensures that you are always informed of the conditions in your offices, server rooms, warehouses and factories, and everywhere where is necessary to monitor the supported values. By connecting directly to a computer network the thermometer or humidity meter can be integrated into the control systems of different manufacturers using SNMP, MODBUS TCP, SOAP, syslog. Of course data in many formats is also available, for example XML and so on.
