Temperature and Humidity Transmitter with External Probe, RS485 Output
Measured values are converted to RS485 serial output. Transmitter circuitry is galvanically isolated from power circuitry to prevent collision in RS485 network.
Serial output RS485 - transmitter works with ModBus RTU communication protocol or with Advantech ADAM compatible protocol. Protocol is user selectable in special configuration mode by means of the PC. Serial link enables to read actual readings and modify transmitter configuration. Instrument works always in slave mode, i.e. responds only to master device query. Transmitters have the address space available from 1 to 255. Communication speed is 110 to 115200Bd.
Humidity, temperature transmitter with T+RH probe on the cable. Outdoor, indoor use.
Humidity, temperature probe on a cable. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.
The device is supplied with a T+RH probe with a 1m cable. Cable lengths 2m or 4m are available optionally.
Programmable temperature and humidity transmitter is equipped with temperature and relative humidity sensors. Degrees Celsius and Fahrenheit are user selectable. Transmitter contains a microprocessor-based control circuitry in a durable plastic case with connection terminals and sensors in a probe on a cable. Sensors are protected with a filter with stainless steel mesh. Large dual line LCD for simultaneous display of T+RH or other humidity interpretation is an advantage. Display is possible to switch off. The computerized design ensures temperature compensation of the humidity sensor and fails indication. State-of-the-art capacitive polymer sensor ensures excellent calibration long-term stability, inertia against water, and condensation. Transmitters are designed for use in non-aggressive environment.
