Temperature and Humidity Bar Type Transmitter with RS485 Output
Humidity, temperature transmitter. Outdoor, indoor use. Bar type.
Relative humidity, temperature sensors at 700mm stem. Measured values are also converted to other humidity interpretation: dew point temperature, absolute humidity, specific humidity, mixing ratio, specific enthalpy.
Programmable temperature and humidity transmitter is equipped with temperature and relative humidity sensors. Measured values are also converted to other humidity interpretation – dew point temperature, absolute humidity, specific humidity, mixing ratio, or specific enthalpy. Degrees Celsius and Fahrenheit are user selectable. Transmitter contains a microprocessor-based control circuitry in a durable plastic case with connection terminals and sensors 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. 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.
Programmable transmitters and transducers with RS485 galvanic isolated serial interface are designed to measure temperature, relative humidity, and barometric pressure of air in a non-aggressive environment. Transmitters and transducers are available in wall-mount, duct-mount, and bar versions or with a probe on a cable. For measuring temperature and relative humidity of compressed air is used type TxxxxP.
Digital conception with microprocessor allows determining the other computed humidity values, like dew point temperature, absolute humidity, specific humidity, mixing ratio, and specific enthalpy. Measured and calculated values are displayed on a two-line LCD display. Devices support Modbus RTU protocol, protocol compatible with standard Advantech-ADAM, ARION protocol, and communication with HWg-Poseidon devices.
Durable plastic case from ABS contains electronic and connection terminals. For easy connection/disconnection of the output, the cable is used TxxxxL version with Lumberg connector (IP67) instead of a cable gland.
