Pantech Instrument’s Model 901 is a DUO of Humidity & Temperature sensors. High grade Humidity & Temp. sensing elements are put in a Probe / User defined structure, with direct connectivity to the upper layer controlling devices / systems. Model 901 series Sensors are designed specifically for high volume OEM users. With HUMIDITY as an alone parameter, direct input to a controller or other device is made possible by this sensor's near linear voltage output.. With a typical current draw of only 200 muA, the Model 901 series is often ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. The basic HUMIDITY sensor inside the probe gives quality RH ( Relative humidity ) sensing performance in a competitively priced package. The RH sensor is a laser trimmed, thermoset polymer capacitive sensing element with on-chip integrated signal conditioning. The sensing element’s multilayer construction provides excellent resistance to most application hazards such as wetting, dust, dirt, oils and common environmental chemicals. For TEMPERATURE measurement, a miniature but high quality RTD is installed inside the basic sensor.
