The PTB-1000™, Pressure Transducer Board, is a four-channel test instrument for measuring differential pressure in enclosures where air flow integrity is critical to proper performance. As the demand for more energy efficient cooling grows, the need for measuring the pressure at each source of heat generation will follow.
In thermal characterization applications, the PTB-1000™ is capable of measuring pressure drop across channels in circuit cards and assemblies; differential pressure across Pitot tubes, orifice plates and venturi tubes; intake to exhaust pressure drop in forced convection cooling systems and pressure drop across in-line filters, to name a few.
The system is available in two pressure ranges; 0-0.15 psi and 0-0.30 psi, the ideal for precise measurements within telecommunications, networking, embedded computing and other high performance electronic applications. Custom pressure ranges are also available, with ranges up to 100psi. Data accuracy is within 1% of the full scale. The pressure transducer is capable of measuring pressure at temperatures from -40° to 120°C with data accuracy within 1% of full scale.
The PTB-1000™ pressure transducer connects to a PC via a USB socket to acquire power and data communications. It can be powered by a 5 volt power supply and provides four independent 0-5V analog output signals proportional to the pressure of each channel. These features enable the system to be easily integrated into other control circuits that require analog voltage as input signals.
The PTB-1000™ includes user-friendly stagePRESSURE™ application software, which provides easy data viewing and logging. The user can save four channels of pressure data as a function of elapsed time for study of raw data history.
ATS also offers its pressure transducer an enclosed module, the PTM-1000™, for OEM applications or system integration.
