Beck. Differential pressure transmitter for air

Product catalog summary

General Description: The 982R series differential pressure transmitters are designed for measuring differential pressure, overpressure, and vacuum. They feature an adjustable pressure range and provide an output signal.

Applications: These transmitters are suitable for monitoring gaseous, non-combustible, and non-aggressive media. Common applications include building automation, air conditioning systems, clean room monitoring, valve and flap control, filter, ventilator, and blower monitoring, and air flow control.

Key Features:

Adjustable Pressure Range: The pressure range can be reduced to 50% of its factory set full scale value using a push-button.
Output Signal: Options include 0-10 V or 4-20 mA, with other signals available upon request.
Offset Calibration: Easy zero calibration via a push-button when the transmitter is depressurized.
Configurable Response Time: The response time can be adjusted using a jumper for either slow (factory setting) or fast response.
Volume Flow Measurement: The output signal can be programmed to a square root shape by the factory.
Reset Function: The transmitter can be reset to factory settings by pressing the push-button for more than 10 seconds.

Technical Specifications:

Measuring Method: Piezoresistive pressure transducer.
Mounting Position: Can be mounted in any position with zero offset calibration to eliminate position error.
Supply Voltage: 18-30 VAC/VDC for 3-wire version, 18-30 VDC for 2-wire version.
Output Signal: 0-10 V or 4-20 mA for 3-wire version, 4-20 mA for 2-wire version.
Maximum Current Draw: Less than 40 mA for 3-wire/0-10 V, less than 60 mA for 3-wire/4-20 mA, less than 21 mA for 2-wire/4-20 mA.
Medium: Air and non-combustible, non-aggressive gases.
Temperature Range: -20 to 70°C.
Linearity: ≤ ±0.5% FS, minimum ±1 Pa.
Uncertainty: ±1% FS, minimum ±1 Pa.
Long-term Stability: ≤ ±1% FS.
Humidity: 0-95% relative, non-condensing.
Response Times: Standard 1.0 s and 0.2 s.
Process Connection: 6 mm hose connection.
Electrical Connection: Spring terminals for wires and leads up to 1.5 mm² or circular connectors M12/4-pole.
Housing Material: ABS.
Dimensions: Approximately Ø 66 x 28 mm.
Weight: Approximately 50 grams.
Protection Class: IP54 with protection cover.
CE Conformance: EMC Directive, RoHS Directive.

Pressure Ranges: Various models available with pressure ranges from 0-100 Pa to 0-100 kPa, each with specific overload and bursting pressures.

Order Matrix: Configurable pressure ranges and output signals with supply voltage options are provided, along with electrical connection types.

Accessories: Includes Climaset® kits with hoses and pipes, duct connecting pipes, angled metal pipes, rubber grommets, and rolls of PVC or silicone hose.

Terminal Assignments: Detailed terminal assignments for 3-wire and 2-wire configurations are provided.
