Yuden-Tech Co., Ltd. (eyc-tech) products

Adopting the differential pressure principle for air flow measurement. Enable bi-direction air flow measurement. Measures differential pressure, pressure, and temperature simultaneously. Calculate medium density and mass flow rate. Rugged and durable design for high temperature and high-pressure environment.

IP65 , rugged aluminum case, fit in variety harsh environment. Capable of temperature compensation. Linear adjustment temperature & humidity by computer, analog output or option RS-485. Measure high accuracy Temp. & humidity, reaction quickly, the sensor can work well after temporary condensation, long term stable in high humidity environment. Process Temp. : up to 200°C, S.S. probe proof pressure : 10 bar, metal connector : installation repeatedly. Switch multifunction physical quantities:[%RH] [°C] [mbar] [g/kg] [g/m3] [kj/kg]. Calibration physical quantities, measuring range, analog output, station, etc. Free calibration software : data logger / record 65535 datas / charts.

Dew point calibration, highly accuracy, 4 ... 20 mA and RS-485 output. Reduce insensitivity temperature zone, quickly response. Hysteresis compensation, resistance to moisture, extreme high and low humidity impact. EMC anti-interference, anti-condensation, low-temperature influence, long-term stability. Three thread (1/2″PT, 1/2″G, and 5/8″UNF) mode can be selected.

The eyc-tech PHM330 differential pressure transmitter is designed on thermal mass flow sensor, which is excellent on measuring very low differential pressure, and has great zero point stability and high pressure resistance. PHM330 allows a very small amount of gas flow through its sensing part, then converts flow measurement signal to differential pressure measurement signal via the integrated circuit.
