Differential pressure sensor

  • Pressure-linear characteristic with selectable pressure measuring range
  •  Operating voltage AC 24 V or DC 13.5…33 V
  •  Output signal DC 0…10 V
  •  Zero-point adjustment
  •  Simple and fast mounting thanks to integrated mounting brackets in the housing
  •  Maintenance free
  •  Calibrated and temperature-compensated measuring signal Supplied with tubing connection set Application

Immersion Temperature Sensors

  • Active sensors for acquiring the water temperature in pipes and tanks
  • Operating voltage AC 24 V or DC 13.5…35 V
  •  Signal output DC 0…10 V or 4…20 mA
  • The sensors are for use in ventilation and air conditioning plants for:
  •  Controlling or limiting the flow temperature
  •  Limiting the return temperature
  •  Controlling the DHW temperature

Air velocity sensor

  • This sensor is used to control the air velocity to a constant value, or to balance out
    pressure fluctuations (supply or extract air control), or to monitor the flow in air ducts.
    It primarily is used for modulating fan control in primary plants to set the basic volume
    flow.

Flow switch

  • Contact load: max. AC 230 V, 1 A, 26 VA
    DC 48 V, 1 A, 20 W
    · Nominal pressure PN10
    · Manual contact setting (NO/NC contact)
    · Housing protection type IP 65 / Protection class II
    · Maintenance free

Flow sensor

  • Vortex flow sensor made from fiber-glass-reinforced plastic
  • Output signal: DC 0…10 V or 4…20 mA
  •  Flow range: 1.8 …150 l/min
  •  Used for temperature ranges: -15…+125 °C
  •  Operating voltage: DC 18…33 V (QVE2100…) or 11.5…33 V (QVE2000…)
  •  Temperature-insensitive measuring principle
  •  No moving parts
  •  Low pressure loss
  •  Insensitive to soiling

Room Hygrostats

  •  Hygrostat with single-pole microswitch
  •  Humidity measuring element made of stabilized plastic texture
  •  Setpoint knob for the upper switching point
  •  For controlling humidification equipment
