The new mini transmitters are built on Orange Research’s proven design, using the same pressure bodies and sensors that make it the #1 OEM differential pressure indicator and switch. The same transmitter technology used in larger models has been incorporated into these miniature products to provide an attractive, low-cost alternative.
Both models offer transmitters with current or voltage output, rated at 4-20 mA or 0-5 V. The models have an accuracy of 10% (5% repeatability), optional 1” diameter durable plastic dial cases, and 1/8” NPT porting (many options available). Model 1002, with a piston sensor, has a DP range of 0-4 to 0-75 psid and a maximum line pressure rating of 3000 psig. Model 1020, with a diaphragm sensor, has a DP range of 0-25” water to 0-10 psid and a maximum line pressure rating of 1000 psig. If 2% accuracy is needed, standard size DP transmitter models are available.
