Product description The MH-4 model meets high requirements for high-precision measurements within the temperature range of -40 ° C to+125 ° C [-40...+257 ° F]. The sensor has up to three times the overpressure limit, can withstand hydraulic peaks, and can be optionally equipped with a flow limiter. Thanks to the metal shielding, the MH-4 model operates without interference at field strengths up to 100 V/m. In addition, vibrations up to 40 g and impacts up to 100 g have no effect on the measurement quality. Developed specifically for the specific requirements of mobile work machinery. Whether it's dust, humidity, heat, or mechanical stress: The MH-4 pressure sensor is optimized for mobile use, making it particularly safe to operate and therefore consistently reliable. The maintenance free instrument design ensures a particularly low total cost of ownership. MH-4 is designed for over 100 million load cycles, with a long-term drift of less than 0.1% FS. Featured Features Developed specifically for extreme operating conditions of mobile work machines. Reliability and highest precision throughout the entire lifecycle. Customer specific adaptation and personalization. High production capacity. Key Advantages Extreme Durability: Withstands 40g vibration and 100g shock; designed for >100 million load cycles. High Accuracy: Non-linearity ≤ ±0.25% FS (BFSL); long-term drift ≤ ±0.1% FS. Wide Temp Range: Operates reliably from -40°C to +125°C. High Overpressure Protection: Up to 3× nominal range (≤400 bar) to handle hydraulic pressure spikes. EMI Protection: Metallic shielding immune to up to 100 V/m electromagnetic fields. Maintenance-Free: No servicing required; low total cost of ownership. Compact & Welded Stainless Steel Body: IP6K9K ingress protection; easy OEM integration. Versatile Integration Construction Machinery: Excavators, cranes, loaders, MEWPs. Agricultural & Forestry: Tractors, harvesters, forest equipment. Electrical Connectors: AMP Seal 16, Micro Quadlok, Econoseal J, VW 4-pin, or cable outlet. Measuring Ranges: 0…40 bar up to 0…1,000 bar (500–10,000 psi). For quotation, send the complete order code, quantity and operating conditions. Specifications and available options depend on the ordered configuration.
