TDWLB Wireless Pressure/temperature Sensor

The new TDWLB pressure/temperature sensor designed by Transducers Direct is the industry's first to be powered with a coin-cell battery, controlled with a smartphone app, and certified as Bluetooth® Smart. The TDWLB senses pressure by using a time-to-digital converter (TDC) to measure the duration of a capacitive discharge across the changing resistance in a Wheatstone bridge atop the diaphragm. Clever circuitry splits the signal from the bridge, creating a redundant signal that ensures continuous machinery operation if one half should fail. All wetted parts of the TDWLB are stainless steel. The sensor is EMI/RFI protected and sealed to IP-67 rating. Standard overpressure rating is 2X, with 4X 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.
