Banner Engineering: QM42 Differential Pressure Sensor


February 14, 2022

Banner has expanded the measurement range of its QM42-DPS Differential Pressure Sensor line to include +/- 20 inWC. In addition, the company now offers the sensor in the RS-485 modbus communication protocol for all measurement ranges. The RS-485 option allows users to add this sensor to a modbus network for complex monitoring applications, while the 1-wire serial sensor can transmit the data to a wireless controller or a gateway using the Q45DPSD transmitter for remote monitoring.

The QM42 Differential Pressure Sensor offers accurate low-differential pressure measurement of air and non-condensing, non-corrosive gases in applications such as air filter monitoring, isolation and clean rooms, building pressurization and dust collectors.

  •    –   The differential pressure sensor is used to measure the difference in airflow between intake and exit – such as airflow through a filter – to make decisions on preventive maintenance or to maximize efficiency of industrial equipment.
  •    –   The QM42-DPS1-2Q model senses up to +/- 1 in WC, using RS-485 Modbus serial communication
  •    –   The QM42-DPS20-2Q model senses up to +/- 20 in WC, using RS-485 Modbus serial communication
  •    –   The QM42-DPS1-1Q model senses up to +/- 1 in WC, using 1-wire serial communication with Q45DPSD transmitter node
  •    –   The QM42-DPS20-1Q model senses up to 20 +/- 20 in WC, using 1-wire serial communication with Q45DPSD transmitter node

Siemens: SIMOVAC Non-Arc-Resistant and SIMOVAC-AR Arc-Resistant Motor Controllers

The Siemens SIMOVAC medium-voltage non-arc-resistant and SIMOVAC-AR arc-resistant controllers have a modular design incorporating up to two 12SVC400 (400 A) controllers, housed in a freestanding sheet steel enclosure. Each controller is UL 347 class E2, equipped with three current-limiting fuses, a non-load-break isolating switch, and a fixed-mounted vacuum contactor (plug-in type optional for 12SVC400). The enclosure is designed for front access, allowing the equipment to be located with the rear of the equipment close to a non-combustible wall.
