JC30 is an industrial measuring instrument that is modular in design and meets global OEM standards. The series is stable and reliable, and has excellent cost performance. It is rugged and durable to meet the requirements of more stringent industrial standards. It is widely used in industrial support, industry support and equipment support. The series includes a variety of options, which are applied to different industries and different working conditions. It solves the needs for economic pressure monitoring in different occasions and serves a wide range of industries.
JC30 air pressure / micro differential pressure transmitter adopts new technology to produce micro range, high stability silicon piezoresistive non-oil-filled sensor components and special digital integrated circuits. It is firmly packaged with 304 stainless steel casing through stress isolation technology. The measured air pressure or differential pressure enters the positive and negative pressure chamber of the sensor through the G1/4 external thread or φ6 integrated barbed tower pressure interface, and the corresponding air pressure or differential pressure is converted into a plurality of industrial standard signal outputs proportional to the sensor detection, Such as 4 ~ 20mA, 0-5V DC, 0.5-4.5V DC.

(JC30 Air Pressure/ Micro Differential Pressure Transmitter; Range 0~1MPa Gauge; Output 4~20mA; Accuracy 0.5% typical; Power Supply 9~30VDC;Pressure Connection G1/4 male thread; Electrical Connection M12 corner out 1m;  Selection Remarks: The range meter 01KP=1KPa G/D G indicates the gauge pressure or wind/air pressure, which is the pressure difference with the atmosphere, that is, the wind pressure measurement of a single pressure port, D is the differential pressure measurement, measuring the pressure difference between the two pressure ports. Use the B-copper joint in the outline drawing to connect the negative pressure port, as shown in the outline drawing.
Remarks: It can be customized if the order quantity exceeds a certain amount. Please contact the sales engineers for details.
