Who is Huba Control and what does it make?
Huba Control is a Swiss manufacturer of pressure and flow sensors headquartered in Würenlos, active since 1945. The programme covers pressures from about 1 mbar up to 1000 bar and flows from 0.5 to 240 l/min, and at its base is the thick-film measuring cell, made of Al2O3 ceramic or stainless steel, produced in series since 2002. For a maintenance engineer, the importance lies in the large number of mechanical and electrical variants: the same measuring principle ends up in air conditioning, refrigeration, hydraulics and water treatment installations.
Differential pressure transmitters are the family used in ventilation and in clean rooms. They use piezoresistive sensors with a silicon membrane and Wheatstone bridge resistors, and measure small differential pressures in air and neutral gases, from 20 Pa to 15,000 Pa; the 401, 402, 450, 652, 664, 692, 698 and 699 series include devices with adjustable ranges and variants with Modbus.
Vortex flow sensors measure low- and medium-viscosity liquids on the Kármán vortex street principle, with no moving parts, with a response time of at most 5 ms and internal temperature measurement for viscosity compensation. The housings are available in plastic, stainless steel, brass and bronze. The quotation is prepared according to the measured quantity, range, medium, connection and output signal.
What do we supply from the Huba Control range?
| Product | Description |
|---|---|
| Differential pressure transmitters (401, 402, 450, 652, 664, 692, 698, 699, 699M) | Piezoresistive devices for air and neutral gases, from 20 Pa to 15,000 Pa, with adjustable ranges and variants with a Modbus interface. They are used for monitoring filters, the airflow in ventilation ducts and the pressures in clean rooms and laboratories. |
| Pressure transmitters (503–578) | Compact stainless steel devices for liquids and gases, from 50 mbar up to 1050 bar, with a ceramic or metal cell. Gauge and absolute pressure, overpressure and vacuum measurement are available, plus mechanical connection and electrical signal variants; the series also includes the 521 and 529 electronic pressure switches. |
| Vortex flow sensors (200–240) | Sensors with no moving parts for flows from 0.5 to 240 l/min. Types 200 and 235 have variants compatible with the R290 refrigerant, and type 240 is PFAS-free (per- and polyfluoroalkyl substances), for system pressures up to 16 bar and temperatures up to 125 °C. The housings are made of plastic, brass, bronze or stainless steel. |
Why Huba Control?
- Very small differential pressure ranges — the transmitters start at 20 Pa, suitable for filters, fans and clean rooms
- Adjustable ranges and Modbus — some of the differential pressure transmitters have adjustable measuring ranges, and some variants have a Modbus interface
- Vortex sensors with no moving parts — response of at most 5 ms and viscosity compensation through the temperature measured inside the device
- Housings for several media — plastic, brass, bronze or stainless steel, depending on water, refrigerants or aggressive liquids
- Pressure from 1 mbar to 1000 bar — ceramic or steel cells, with a very large number of connection and electrical interface variants

How do we supply Huba Control in Romania?
We can quote Huba pressure and differential pressure transmitters and vortex flow sensors, starting from the type on the nameplate. We bring them in to order, through EU supply channels, usually in 1–4 weeks, and a variant with a special connection or signal may take longer, depending on the brand and the specifications. For a correct quotation, send us the type of the existing device or the measured quantity, the range in Pa, mbar or bar, the medium, the connection, the supply and the output signal (analogue or Modbus). If you want a new device, add the working temperature and the protection rating required.
A variant with a special interface or connection is determined on the basis of the exact type of the device.
Frequently asked questions about Huba Control
What does Huba Control manufacture?
Huba Control manufactures pressure and flow sensors: pressure and differential pressure transmitters, hydrostatic level transmitters, mechanical and electronic pressure switches, measuring cells and vortex flow sensors. The company is based in Würenlos, Switzerland, and has been operating since 1945.
What differential pressure range should I choose for a ventilation duct?
The range is chosen according to the actual pressure in the duct or across the filter, with a margin above the working value. Huba transmitters for air start at 20 Pa, and some of them have adjustable ranges. Send us the working pressure, the type of filter and whether you need volumetric flow.
Do you supply Huba products in Romania, and within what lead time?
Yes, we bring in the devices to order, through EU supply channels, usually in 1–4 weeks; the lead time is 24–72 h when the item is available locally or at the supplier. For variants with an unusual connection or signal, the lead time may be longer, depending on the brand and the specifications.
Can I replace an older Huba transmitter with a new series?
It depends on the range, connection, supply and output signal. We do not declare equivalence by number; send the type from the device, the range and a photograph of the installation, and we compare the data with the current series and show what can be kept without modifications.
What details do I need to send for a quotation on a Huba sensor?
Send the measured quantity (pressure, differential pressure, flow), the range, the medium and its temperature, the connection, the supply voltage and the output signal, for example 4–20 mA, 0–10 V or Modbus. For a vortex sensor, add the nominal diameter and the liquid.
How do I request a Huba Control quotation?
Send the Huba Control code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
