Dpstar is an authorized distributor of Setra Systems. We provide our customers with the best selection of instrumentation and equipment with unrivaled prices to perform in Pressure Sensing Solutions. Setra’s pressure sensors are known for their quality and reliability. Setra is designed with premium capacitive sensing technology and offers single-range and multi-range (field-selectable) pressure sensors. Capable of measuring both liquid and gasses, Setra has the product to meet a breadth of HVAC applications and can be trusted in your most critical applications. Trust Setra’s over 50 years of pressure transducer engineering excellence.

The Setra FLEX™ provides a flexible room environmental control and monitoring solution in a simple-to-use package. An attractive flush-mount faceplate is complemented by an intuitive graphical display to meet any architectural requirement. The unit supports 3 rooms, monitoring up to 6 parameters for each room. An optional differential pressure sensor can be either factory-installed in the unit or ordered separately and installed above the ceiling. Integration with building automation systems is made easy through either BACnet/IP or BACnet MS/TP network protocols.


Key Benefits

  • Modular design
    A modular hardware design enables the FLEX monitor to fit in various wall thickness found around the globe. For applications which require the
    monitor to fit in wall depths less than 50mm, the FLEX can be ordered with an external pressure sensor. When mounting in a three-gang electrical box, the FLEX can be ordered with an integrated onboard sensor. Sufficient onboard I/O provides connectivity for most common equipment and sensor applications. If additional connections are required, or if more advanced HVAC applications demand it, FLEX can work directly with a third-party controller over BACnet. A high accuracy 0.25% differential pressure transducer is used in all pressure sensing options. A projected capacitive touch screen provides swipe functionality and allows for use with medical gloves. The faceplate is attached to the unit body, enabling both tamper-resistant operation and easy opening for pressure calibration.
  • Setra FLEX-RM and FLEX-RC
    FLEX software is designed to suit any application, with the ability to support up to 3 rooms. FLEX-RM (Room Monitor) provides monitoring only, for those applications where no control from the touch screen is needed. FLEX-RC (Room Control) offers monitoring, plus PI loop or network control of VAV boxes, venturi valves, or hydronic reheat valves. Software is preinstalled, with configuration and network integration done using simple setup screens. There is no programming required. When completed, configuration settings on one unit can be cloned to other devices using a standard USB thumb drive, thereby shortening commissioning time. Units can also be configured remotely over a BACnet network. The FLEX monitor is both a controller and monitor, with audible and visual alarming on all room environmental parameters. The FLEX monitor enables users to save energy by choosing from a PI control loop or three BACnet Setpoint Override control points and two monitoring sets for any of four room modes, such as occupied and unoccupied.
