    Pressure proof stainless steel probe porous housing for 4-20 ma digital display intelligent soil humidity sensor probe


    HENGKO stainless steel sensor housing are made by sintering 316L powder material in high temperature. They have been widely used in environmental protection, petroleum, natural gas, chemical, environmental detection, instrumentation, pharmaceutical equipment and other fields.

    HENGKO stainless steel sensor porous protection guard have excellent performances of smooth and flat internal and external tube wall, uniform pores and high strength. The dimensional tolerance of most models is controled within 0.05 mm.

    HENGKO digital temperature and humidity module adopts high precision SHT series sensor euipped with a sintered metal filter shell for large air permeability, fast gas humidity flow and exchange rate. The shell is is waterproof and will keep water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity (moisture) of the environment. It has been widely used in HVAC, consumer goods, weather stations, test & measurement, automation, medical, humidifiers, especially perform well in an extreme environment like acid, alkali, corrosion, high temperature and pressure.

    HENGKO temperature humidity sensor probe housing have excellent performances of high precision:temperature +-0.1°C, humidity +-1.5%RH,  multiple output: RS485 , 4-20mA, 0-10V , 0-5V, switching value …… ,  various SHT sensor optional, wireless and wired, various probes optional,various sensor housings optional.

    Product Description

    1. Large air permeability, fast gas humidity flow and exchange rate,  uniform divergence.  it is far superior to other peer products with the optimization of special process in HENGKO.

    2. Excellent ability of anti-dust, anti-corrosion and waterproof(IP65)

    3. Protecting PCB modules from dust, particulate pollution and oxidation of most chemicals to ensure sensors a long-term stable operation, higher reliability and long service life

    4. Remarkable performance in harsh environment such as small space, long distance space, pipe, trench, wall pass mounting, high pressure space, vacuum chamber, test chamber, large flow mediums, high humidity area, high temperature and heat environment, hot drying process, dangerous zones, explosive environment containing explosive gas or dust, etc

    5. 150 bar anti-pressure capability

    6. Seamless integrated, shedding-free

    7. the HENGKO stainless steel porous houisng for sensor probe, have accurate pore size, uniform and even-distributed apertures. Pore size range: 5μm to 120 micron; it have good filtration dustproof and interception effect, high filtration efficiency. The pore size, speed of the flow and other performances can be customized as requested; Stable structure, particles are tightly bound without migration, almost inseparable under harsh environment.
