New Android App Allows Remote Monitoring and Programming of CirrusSense® Pressure Transducers

Check pressure of refrigerants, water, oil, industrial gasses, etc. on mobile devices.

CINCINNATI, Ohio — Transducers Direct introduces its new Android app for remote monitoring and programming of the CirrusSense® TDWLB pressure transducer, the first sensor in the world to use wireless Bluetooth LE and a patent pending design to connect pressure sensors to mobile devices and computers. The new app ("CirrusSense TDWLB" on Google Play) lets the user name each sensor, then program setpoints/alarms for multiple sensors and monitor readings – all from any Android-enabled device. The CirrusSense® sensor is ideal for remote reading of pressure/temperature in A/C and refrigeration lines, compressed air lines, water lines, dental and industrial gas lines, etc. It uses patent-pending circuitry to provide a 12 to 18 month battery life and redundant sensing. The sensor is available in two different compensated accuracies of 1 percent and 0.25 percent, with an external temperature sensing probe as an option for measuring sub-cooling and superheat in HVAC applications. The CirrusSense transducer is certified Bluetooth® Smart, as well as FCC certified.

"The pressure of any fluid can be remotely monitored with CirrusSense," said Rob Matthes, President of Transducers Direct. "Users save time and money by preventing equipment damage, food spoilage, unneeded service calls, downtime, and premature refills. The sensor also ends refrigerant leaks and blowback from manifold gauges, so it's EPA friendly. There's no gauge recalibration or adjustment. There has never been anything like this, and we'll be announcing new capabilities for this platform in coming months."

The US-made CirrusSense TDWLB is all digital, eliminating mechanical components, wear parts, analog circuitry and setpoint drift. It is easily programmed and monitored through its app for measuring pressures from vacuum to 10,000 psi. The sensor is EMI/RFI protected and sealed to IP-65 rating. Standard overpressure rating is 2X, with 10X optional. Burst pressure is 5X or 20,000 psi, whichever is less. The TDWLB is available with a variety of industry standard pressure-port connections. Replacement battery packs are available from Transducers Direct.
