BP133 series pressure transmitterDetailed product description：

Product Introduction

The BP133 series pressure transmitter adopts imported ceramic sensors, among which the BP133-A type uses a piezoresistive ceramic diaphragm, and the BP133-B type uses an E+H capacitive ceramic sensor, coupled with high-precision electronic components, assembled through strict process. Compared with conventional pressure transmitters on the current market There are two significant technological differences, one is that the measuring element uses emerging ceramic materials, which will not cause process pollution to the measuring medium The second is that there is no intermediate liquid inside the measuring element, which is completely fixed The medium pressure directly acts on the ceramic diaphragm, causing displacement of the measuring diaphragm and resulting in a change in capacitance. This change is detected, amplified, and converted into a standard signal output by the electronic components connected to it. Under normal pressure, the diaphragm is offset by 0.025mm; under overpressure, the diaphragm is offset by 0.1mm. At this time, the measuring diaphragm is attached to the ceramic bracket and protected to avoid damage

10 intrinsically safe explosion-proof, explosion-proof grade iaIICT4;
1L shell protection level: IP65
The variety of two-wire 4-20mA output has a standard power supply of DC24V. When the load resistance is greater than 600 Ω, an additional 1V power supply is required for every 50 Ω increase, but the maximum power supply limit is DC45V. When more than DC24V power supply is needed, the output circuit should avoid long-term operation in a zero load resistance state. If necessary, a resistor can be connected in series in the output circuit to reduce the power consumption of the output power transistor Minimum supply voltage DC12V at zero load resistance
