MICRO LOW DIFFERENTIAL PRESSURE TRANSDUCER PT-105A-A

The differential pressure gauge delivers 

precise measurements in the 200Pa full 

scale range. Capable of measuring 

pressures as small as 0.1Pa, 

the instrument is ideal for use as a pitot 

tube or differential pressure sensor 

in orifice flow rate measurements. 

The robust design ensures an overpressure 

safety of 10 times the full scale value.

♦ Measurement range : 200Pa

♦ Pressure media : 

Air and non-corrosive gases

♦ Accuracy : ±0.15% of F.S

♦ Permissible overpressure : 

10 times F.S.

♦ Power source : 

± 15 VDC, 20mA or less

♦ Output voltage : 

2V for 200Pa range

COSMO INSTRUMENTS

DP GAUGE (DIGITAL PRESSURE GAUGE) DP-340BA

DP-340BA is applicable to a wide 

range of pressures from a micro 

differential pressure (500Pa) to high 

gauge pressure (50MPa). This is a digital 

pressure gauge with a high-accuracy 

sensor that has the excellent 

overpressure resistance.

♦ Accuracy

Differential Pressure Type : 

±0.3% of F.S ±1digit

Gauge Pressure Type : 

±0.25% of F.S ±1digit

♦ Pressure Media

Differential Pressure Type : 

Air, Noncorrosive Gases

Gauge Pressure Type : 

Air, Noncorrosive Gases, and Liquid

*Digital Output

With RS-232C and the parallel binary 

coded decimal (BCD), data can be 

transferred to the external device
