Features
Baratron® Capacitance Manometer Technology
Capacitance manometers are electro-mechanical gauges that can measure both pressure and vacuum. The capacitance gauge translates a pressure-modulated movement in a thin diaphragm into an electrical signal proportional to the pressure. The pressure sensor is the thin diaphragm that is exposed to the pressure or vacuum being measured via the inlet tube. An electrode is mounted in the reference cavity behind the diaphragm. Pressure differences between the process and the reference cavity deflect the diaphragm slightly, changing the distance between it and the electrode. Variations in this distance produce variations in the capacitance between the diaphragm and the electrode creating an electrical signal that is proportional to the pressure change. Since differences in the capacitance signal are produced by physical changes within the manometer and not by changes in the gas properties, pressure measurements by the capacitance manometer are independent of the composition of the gas being measured.

Percent of Reading Accuracy
Accuracy is specified as a percent of Reading, not Full Scale, as seen in some of the lower performance devices. Percent of Reading accuracy provides you with an even more accurate output signal in the lower scale of the pressure range, where it is needed most.
Explosion Proof Rated Enclosure
The 430e Baratron® absolute pressure transmitter features a NEMA 4 (FM17US0326) approved housing and flame snubber for use in applications requiring an explosion-proof or weather-proof transmitter. It is approved for Class I, Divisions 1 and 2, Groups C and D explosion-proof applications. The housing is made with 356-T6 aluminum (NEMA 4) and coated wirh 2-part polyurethane paint,
Absolute Pressure Measurement
These Baratron® pressure transducers are referenced to vacuum for absolute pressure measurement. Applications include: vacuum furnaces, freeze-drying of fruits and vegetables, gas lasers, automotive component testing, bottle coatings, and vacuum distillation.
All-Inconel® Wetted Surfaces
These pressure transducers feature all Inconel® construction of the pressure sensor allowing it to operate without damage in virtually any chemical environment, including exposure to halogens, deionized water and steam, and ozone.
4 to 20 mA Output Proportional to Pressure
These Baratron® capacitance manomaters feature a 2-wire linear 4 to 20 mA analog output that is proportional to absolute pressure. 4 mA indicates zero pressure with 20 mA indicating full scale pressure. 24 to 32 VDC power is required, and the 4-20 mA signal is into a 500 Ω load.
