Product Description
Product Overview JCHM24 Economical Pressure Sensor and Transducer is a civil and industrial product with large consumption and low costs, for which a new standard of cost performance has been established. This series of products is widely used for pneumatic and hydraulic detection even in very harsh medium environment such as sewage, vapor, slight corrosive liquid and gas. JCHM24 series is designed with foreign advanced micro-machined silicon pressure-sensitive resistance metal membranes. Micro-melting technology is adopted to solidify the high-temperature glass on the stainless steel isolating membrane. Glass cementation avoids the influence of temperature, humidity, mechanical fatigue and medium on the adhesive and material, thus enhancing long-term stability of the sensor in industrial environment. Meanwhile, the effect of P - N junction in a conventional micromechanical sensor can also be avoided.

Tips for Type Selection:
1. The medium to be measured shall be compatible with the material contacting with the product.
2. As an additional function code for type selection, the code "E" for intrinsically safe explosion-proof type ExiaIICT6 denotes that power source must be supplied via safety barrier
3. For other special requirements, please discuss with us and clearly indicate them in the order.
