Ordering and delivery
When ordering, please specify the quantity, product name and type code.
Example: 1 differential pressure sensor QBE3000-D1
A suitable fixing bracket is supplied with the sensor.
Any accessories required must be ordered separately.
Compatibility
Differential pressure sensors can be used in conjunction with all devices or systems
capable of processing the DC 0...10 V or DC 4...20 mA output signal.
Technology
The pressure to be monitored acts on a ceramic sensor element. The ceramic element
has the following significant advantages
· Very low susceptibility to temperature
· Resistance to high temperature
· No mechanical ageing or creepage
The sensor signal is linearised, temperature-compensated and amplified by the sensor
electronics.
Mechanical design
The differential pressure sensor comprises the following:
· Sensor cover with DIN 175301-803-A connecting cable and gland
· Pressure sensor casing with ceramic element, screw connections and burglarproof
screw
· Printed circuit board
· Pressure connections G⅛“, external threaded with unscrewed fittings for
copper pipe, 6 mm diameter
· Fixing bracket, enclosed loose, with sensor
· Plug DIN 175301-803-A unattached
