Aplisens developed a differential pressure transmitter for level measurement in vacuum tanks based on 2 absolute pressure transmitters:

• Modular construction with possibility of replacing of each module of the measuring system
• Output signal 4 ÷ 20 mA + HART
• Accuracy 0,1%
• Intrinsically safe and ex-proof versions

On/off level switches alert operators when product in a storage vessel hits a certain high or low level to avoid overspilling or a tank running dry.

The Hycontrol Capacitance level sensors ME Series uses the same transmitter and sensor for all applications with adjustable sensitivity on the dielectric constant for simplified product selection, installation and maintenance. Mount it - wire it - forget it.

Hadro manufactures Magnetic level gauges with

• Reed or Microswitch
• Reedchain transmitter with 4-20 MA analog output
• Field-/Profibus or HART protocol
• Intrinsically safe (Exi) or flame/explosion proof (Exd)

The housing can be made of Aluminum or stainless steel with IP68 and LCD or optical display.

Leitenberger, Germany offers a wide variety of electronic pressure switches:

• 

  up to 4 switch contacts
• LED display, IO-Link
• freely configurable switching points & hysteresis delay function, Min/Max value data storage, scalable analog output signal
• Intrinsically safe (Exia for gas), PDVF pressure port
• stainless steel or ceramic sensor, flush models
• vacuum, low, high pressure up to 2200 bar
• for hygienic, medical, Oleo and Petro chemical, high viscosity, paint, HVAC, process engineering

The KEP 1/8 DIN digital panel meters offers a wide variety of

• analog and pulse inputs
• thermocouple and RTD sensor input

displaying rate/totalizer, process and batch control values.

The Hycontrol Reflex VF04 TDR guided wave radar is unaffected by pressure, temperature, viscosity, vacuum, foam, dust, coating or changes in dielectric constant.

Admittance level switches from Hycontrol work with a considerable build up on the probe without false switching. They can distinguish between a coating and product level.
