Resistance sensors are most commonly used to measure seed cotton moisture. The Universal Resistance Sensor can be used for both incoming and after-drying moisture measurement. This sensor is a good choice for measurement locations such as: the module feeder, a feed control, above a gin stand or in the live overflow. When used with a Moisture Mirror, the peak-hold capability of these sensors allows moisture measurement in locations not possible in the past. The current sensor design is based on improvements from our first resistance sensor that was sometimes susceptible to static electricity and hanging on to small sticks and trash.
