Environmental and mechanical characteristics

Structural Design and Working Principles

hardware structure

BPSThe series pressure switch adopts a full metal shell (aluminum alloy or stainless steel)

Pressure sensor: diffusion silicon or ceramic capacitive sensor, with long-term stability (annual drift)≤0.1% FS）

Signal processing unit:16bitADCConversion chip, combined with dedicated algorithms to achieve temperature compensation and nonlinear correction

User interface:LCDDisplay screen (some models), buttons or knobs are used for parameter settings and support on-site debugging

working principle

When the pressure of the measured medium acts on the sensor, the sensor converts the pressure signal into an electrical signal, which is amplified, filtered, and thenMCUProcess it. Trigger switch output by comparing with the upper and lower threshold values set by the user; Simulate real-time output to reflect pressure values. The product supports hysteresis adjustment（0.1%~10% FS）, can avoid misoperation caused by pressure fluctuations

Key performance advantages

High reliability and long lifespan

Adopting a contactless design (electronic switch), the switch life can reach up to1More than 100 million times, far exceeding traditional mechanical pressure switches (usually100Ten thousand times). The sensor uses industrial grade components and undergoes-40°C~+125°CTemperature cycling test to ensure stability in harsh environments

Flexible configuration and adaptability

Support switching between multiple pressure units（barThepsiTheKPaTheMPa）

The switch logic can be customized through software or buttons (such as window comparison, hysteresis mode)

Provide intrinsic safety type（ATEX/IECExCertified model, suitable for explosion-proof areas (such as chemical and oil and gas industries)

Intelligent functions

Partial high model integrationHARTAgreement orIO-LinkInterface, supporting remote parameter configuration and health status monitoring, convenient for industrial Internet of Things（IIoT）System integration. The built-in diagnostic function can monitor sensor faults, short circuits, and other abnormal states in real time, and output alarm signals

Typical application scenarios

Hydraulic system monitoring: used for pressure overload protection of injection molding machines and hydraulic machine tools, real-time monitoring of system pressure and triggering emergency shutdown

Pneumatic equipment control: In automated production lines, control the cylinder action pressure to ensure precise execution of processes such as grabbing and handling

Energy industry: Hydraulic pitch system pressure monitoring for wind power generation equipment, pressure leakage detection for oil pipelines

Water treatment field: Pump outlet pressure control to prevent dry running or overpressure operation

Selection precautions

Medium characteristics: Select sensor material based on the corrosiveness of the medium (such as stainless steel)316LSuitable for acidic and alkaline environments)

Pressure range: It is recommended that the actual working pressure be within the range30%~70%To avoid overload damage caused by approaching the upper range limit

Environmental conditions: Models with cooling devices should be selected for high temperature environments, and protection levels should be ensured for humid or dusty environments≥IP65

Output requirements: Clearly specify the number of switch quantities, analog signal types, and communication protocols (if necessary)HART）

Installation and maintenance recommendations

Avoid severe vibration during installation, it is recommended to use shock-absorbing joints; The sensor should be installed perpendicular to the flow direction of the medium to avoid bubbles affecting the measurement

Regular calibration (recommended annually)1Secondly, it can be achieved throughBarksdaleSpecial calibration tools or standard pressure sources are used for

When cleaning sensors, use non-alcoholic beverages and avoid using corrosive solvents; When wiring, it is necessary to strictly distinguish between power, signal, and ground terminals to prevent short circuits

GermanyBarksdale BPSThe series pressure switch has become the preferred solution in the field of industrial pressure control due to its high precision, high reliability, and intelligent characteristics. Through reasonable selection, correct installation and maintenance, the safety and production efficiency of equipment operation can be effectively improved. In practical applications, users need to combine specific working conditions and fully utilize their flexible configuration functions to achieve precise and intelligent pressure monitoring
