QPress – QOM-DURA 1300 Series
The QOM-DURA 1300 Series is a durable piezoresistive pressure transmitter rated for more than 100 million pressure cycles, built for high-duty industrial and chemical applications. It reads ranges to 1000 bar at ±0.25 % FS with 4–20 mA and Modbus RTU outputs, and the IP65 to IP67 housing handles wet and washdown installations. A choice of G1/4, G1/2 and NPT threads makes it a long-life building block for demanding equipment.
