Indoor pressure measurement becomes easier to integrate when the transmitter is compact, low-power and built around a clear analog output. HD4V8TBARO measures barometric pressure from 600...1100 mbar and converts it into a 0...1 Vdc output for straightforward connection to monitoring or control systems.
The piezoresistive sensor supports reliable pressure tracking with ±0.5 mbar accuracy at 20°C, a response time below 200 ms after pressure stabilization and 1 sec. settling time to 99% of the measure. With current supply below 4 mA and 10...40 Vdc power supply, it fits efficiently into permanent measurement setups.
Designed for wall mounting indoors, the transmitter works from -30°C...60°C and is compatible with air and non aggressive dry gases. It is also suitable for installation in Senseca weather station housings HD32.35, HD32.35FP, HD32.36 and HD32.36FP.
The transmitter uses a piezoresistive sensing element to measure barometric pressure for indoor installations.
The device provides a 0...1 Vdc output. Power connects to +Vcc and GND, while the output connects between Vout and GND.
The housing is designed for wall mounting and has compact dimensions of 60 x 66 x 35 mm with a weight of 100 g
The measuring element is intended for air and non aggressive dry gases, with overpressure resistance up to 2 bar – 30 psi.
The transmitter operates across -30°C...60 °C, with specified temperature drift from -20 °C to +60 °C
