Humidity, Temperature & Dew Point Transmitter with Replaceable Humi-chip Module H3 line and H5 line

Transcription

1 B.T...H./E Humidity, Temperature & ew Point Transmitter with Replaceable Humi-chip Module H line and H line The H and H transmitters determine measurements by means of a highly accurate condensation resistant capacitive sensor integrated in a silicon microchip. This technology provides accurate process measurements, reliability and excellent long-term stability. Accurate ew Point calculation is obtained by the integrated humidity and temperature sensors. The sensor must not be used in presence of chemical contaminants or aggressive compounds. The Humi-chip module that incorporates the sensor can be easily replaced without the need for recalibration; Humi-chip environmental limits: C; Stability: Long-term drift <. RH% per year; Two isolated analogue outputs: selectable for Relative Humidity (RH), Temperature (T), ew Point (P), Temperature and ew Point Temperature difference ( T); Alarm: Relay outptut programmable for UR, T, P, T; Real Time Clock (RTC): to trace events and correctly store data; Serial communications: RS8 Modbus RTU for digital retransmission and PC configuration; Enclosure rating: IP66.

2 Not only Humidity Hardware and functions H and H transmitters can be either wall or duct mounted or remote sensor mounted. The painted aluminum housing with connectors or terminal connections is IP66 rated for industrial applications and field installation. The standard H model measures humidity and temperature on a digital display. Two analogue outputs and serial communications are optional. The standard H model calculates the dew point and the difference between the temperature and the ew Point temperature ( T). Options include alarms, event tracing and data logging. Busses, Interfaces and Gateways H and H transmitters have standard Modbus Protocol RS8 Serial Communications. The serial port enables the operator to connect supervisory software, via PC, to accurately monitor the measurements, alarm status and stored data. For fieldbus connection, Ascon offers two Gateway Manager modules: - X to connect Profibus or evicenet - Y to connect CANopen and Ethernet with ModbusTCP protocol and possible integrated Webserver.

Connections: screw terminals with M6 conduit or pole M connectors Stainless steel sintered filter Teflon filter Event storing and ata logging The H model stores event details and ata Logging. Alarm event details including measured values, date, time and duration are stored using the internal Real Time Clock (RTC). Measured ata Logging values are stored on an operator determined cycle. The FIFO memory writes data to an EEPROM that cannot be modified by the operator. The Alarms The H model allows the operator to configure up to alarms which can be combined with any of the system measurements: Humidity, Temperature, P, T and Humi-chip break. Each alarm can be configured as minimum or maximum, absolute, deviation or band threshold, istantaneous or delayed, inhibit at activation (Blocking) or acknowledge (Latching). Alarms can be addressed to a relay output. Aligning Transmitters are factory calibrated and no further calibrations are required even after replacing the Humi-chip sensor. Humidity and/or Temperature measurements can be aligned by using measurements taken from a reference transmitter. The alignment is made on or points and minimizes measurement errors in real working conditions. The easy sensor calibration requires no accessories. chip Module itive sensor, accurate, moisture resistant Storerooms to ripen and preserve fruit and vegetables...
