Wireless Bluetooth Pressure Transducer Perfect for HVAC Monitoring

by Dwain Jackson
Technical Sales Manager, Transducers Direct

How do you know if your HVAC refrigerant pressure is in good shape? You don’t – until it gets HOT. That’s like not having a fuel gage in your car and calling someone every time you need a reading.

Transducer Direct’s TDWLB, the first wireless Bluetooth pressure transducer of its kind in the world, has proven to be a perfect fit  for a wide range of HVAC applications, These include residential, commercial, camper, motor home, marine, and commercial refrigeration and freezers including ice cream and walk-ins. The stainless steel construction of Transducers Direct’s TDWLB allows for accurate measurements regardless of the refrigerant used or pressure range selected.

Traditional pressure checks on air conditioning units require gauges, tools, a tank in case of a fill, and charts to get the proper sub-cooling. And gloves are required for refrigerants like R10A, because the pressure and temperature of normal blowback can cause frostbite.

But installing the TDWLB wireless Bluetooth pressure transducer lets you avoid all of those hassles and monitor refrigerant pressure remotely. An installation of the TDWLB is easy, as you can see in the video below. You just remove the low-loss caps, add a simple swivel-T fitting to each charge port, and – as you can see – the TDWLB installs quickly -- and within minutes you’re up and running.


Then you just launch Transducers Direct’s FREE app on your phone or tablet. Simply let the app find your TDWLBs, which you can give a unique and secure name, and all the necessary readings are at your fingertips: 
  • The wireless Bluetooth pressure transducer’s pressure reading, temperature, and battery alert are all right in front of you. You can also set alarms for high and low pressure alerts for each transducer.
  • And because of the certified NIST-traceable high-accuracy calibration, there are no more worries about old gauges – the TDWLB becomes the accuracy standard.
  • An optional temperature sensor provides pinpoint accuracy for subcooling and superheat measurements.
Transducer Direct’s TDWLB can save you money and by eliminating unnecessary service calls and alering you to HVAC issues before they become problems. Why call an HVAC repair person if all you need to do is replace an air filter?


The TDWLB is also EPA-friendly. Normal blowback from a gauge hose is not only dangerous to exposed skin, but releases refrigerant into the atmosphere.

The TDWLB wirless Bluetooth pressure transducer is even IP65 certified, so it can stand up to rain, sleet, and snow – and that makes it perfect for outdoor HVAC applications.

No longer do you have to carry tanks and hoses and gauges to read refrigerant pressure. There’s no blowback. And imagine the convenience with roof units. Just walk nearby with your device and get your readings – without the hassle.

The TDWLB wireless Bluetooth pressure transducer is available from Transducers Direct and manufactured right here in the USA. For more information or to discuss your specific application needs, please contact Transducer Direct’s technical support team members. They will be happy to help you improve performance while lowering your costs.

Magnetostrictive (Non-Contact) Transducers Offer Longer Life, Better Accuracy

by Dwain Jackson
Technical Sales Manager, Transducers Direct

A magnetostrictive transducer is also called a non-contactlinear transducer for precisely that reason: as opposed to a traditional linear transducer that measures resistance by a contact point, a non-contact lineartransducer does the same thing by sensing a magnetic field.


Magnetostriction was first discovered in 1842 by James Joule – yes, that James Joule – and described the change in shape of ferric materials like iron in the presence of a magnetic field.

Today, Transducers Direct uses that technology in sensors. The magnetostrictive sensor is composed of an internal wave guide – about the size of a hypodermic needle –and a protective housing. Outside of the sensor is a position magnet. Inside the wave guide is a current wire that carries a current pulse down the length of the transducer. When the current pulse hits the magnetic field of the position magnet, it triggers a torsion twist -- and sends a signal back to the pickup.

Imagine a guitar string: when you pluck the string it sends the vibration down to the pickup where the result is the note you hear.

Because we know the speed of the pulse around 2800m/sec, the time it takes to get to the magnet and back is all we need to determine position.

What Are the Benefits of Magnetostrictive Transducers?

The primary benefit of magnetostrictive transducers is that they have no contact parts, which results in longer life. They are also more accurate than traditional contact transducers, and better protected in applications that include water spray, wood chips, or other debris.

There is also a downside: magnetostrictive linear transducers have a higher initial cost, require 24 volts from a power source, and in extremely high-speed applications, can show a lag of a few milliseconds.
