Hydrostatic Head

One of the oldest and most common methods of measuring liquid level is to measure the pressure exerted by a column (or head) of liquid in the vessel. We offer solutions with submersible sensors and through the tank wall sensor options.

400 series

The 400 series of submersible pressure transmitters includes a number of completely submersible pressure-sensing transmitter models ranging from 0 to 1m water column to 0 to 500m, that contain an air vent tube for providing a pressure differential relationship between the hydrostatic head and the atmosphere. The transducer contains associated electronic circuitry for providing an analogue output, has an IP 68 protection rating, and requires a 24 Vdc ± 10% Power Supply
One of the regular applications for these transmitters is tank level monitoring & control

 

Ultrasonic sensors provide a cost effective sensing method with unique properties not possessed by other sensing technologies. By using a wide variety of ultrasonic transducers and several different frequency ranges, an ultrasonic sensor can be designed to solve many application problems that are cost prohibitive or simply cannot be solved by other sensors. Ultrasonic sensors continuously emit high frequency sound pulses inaudible to the human ear  which travel away from the sensor, hit the surface of the target and are reflected back to the sensor. The sensor electronics measure the time taken by the signals to return after being reflected by the target surface.

Since the speed of sound is affected by air temperature, our ultrasonic sensors include a built-in temperature sensor. Level/distance measurements are automatically temperature compensated throughout the operating temperature range of the sensor.

Classic applications include proximity sensing, object presence or absence, obstacle detection for automated vehicles, distance measuring, level measuring, etc etc


highlights

  • Direct measuring value output in mm/cm or % via LED display
  • Temperature compensation  for accurate measuring with fluctuating temperature
  • accuracy with temperature drift internal compensation, ±  1%
  • Numerical sensor setting via LED display  for a complete pre-setting of the sensor
  • 1 or 2 pnp or npn switching outputs for all controls
  • Analogue output 4-20 mA and 0-10 V  for two signals in one device (optional), reverse polarity protection
  • Operating voltage 9-30 V for application in various supply networks
  • Additional teach-in-function for a traditional setting of detect points
  • Automatic synchronisation for simultaneous operation of up to ten sensors in confined spaces
  • Automatic switchover between current and voltage output  for simple operation
  • Housing material brass sleeve, nickel-plated, plastic parts, PBT, TPU (stainless steel optional)
  • protection rating IP67
  • vibration & shock complies to IEC 60068-2-27

 

Different operating modes and device configurations enable our ultrasonic sensing systems to be used in most conceivable automation applications
