Pantech Instruments manufactures Humidity cum Temperature Transmitter, Model 901. Pantech Instruments is the manufacturer of Process Control Instruments. Humidity cum Temperature Transmitter is a Predefined I/P Indicator and Controller. It is a Humidity Transmitter plus RTD sensing element. Humidity cum Temperature Transmitter the Sensing plus Transmitter circuits not only senses the percent RH value , but also does convert it into 2-wire 4-20 mA DC signal, for use of the higher instrumentation or controlling layers. Humidity cum Temperature Transmitter has the load capacity of 4-20 mA and DC signal is 600 ohms. The series of Humidity cum Temperature Transmitter is often ideally suited for low drain, battery operated systems. 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 elements and transmitter PCB`s multilayer construction provides resistance to most application hazards such as wetting, dust, dirt, oils and common environmental chemicals. Humidity cum Temperature Transmitter miniature but high quality RTD is installed inside the basic sensor to measure temperature.
