pressure gauge คืออะไร Things To Know Before You Buy

+ The filling liquid is chosen in accordance with the temperature of measuring media, the ambient temperature on the instrument and "no damage" necessities for filling liquid. 

Badotherm pressure gauge design BDT12 is actually a diaphragm type pressure gauge a... Badotherm pressure gauge model BDT12 is usually a diaphragm type pressure gauge and well suited for all gaseous and liquid media, as well as for viscous media and suspended solids.

 The transmitter is usually mounted at grade, or in near proximity to the substantial-pressure process link. The improve in level in tank or vessel inturn results the HP & LP pressure points and this variation in pressure will likely be measured employing a differential pressure transmitter and afterwards calculates equivalent level in the tank or vessel.

Thanks to Taylor’s “All-Welded” technologies in distant seal producing in addition to to your longstanding experience, 266GRT can present unmatched total performances plus a good selection of possibilities which include fill fluid, diaphragm material, capillary safety and mounting connections.

Method measurement sensors are usually not indestructible. Not even probably the most rugged unit is entirely proof against the chemical character of course of action media or perhaps the kinetic impression associated with fluid composition and motion.

Commonly applied: Suited to liquid level measurement of significant temperature and significant pressure, solid diaphragm seal type pressure gauge corrosion together with other media.

Diaphragm seal systems respond to improvements in both approach pressures given that the level modifications from the tank, As well as in static pressure above the liquid. These variants in pressure are transmitted through an oil- stuffed capillary to your differential pressure transmitter-sensor. The capillaries and seals are loaded with incompressible oil appropriate with the process temperature, pressure, and media composition.

Urea is shaped because of the chemical reaction of ammonia (NH3) with carbon dioxide (CO2). The warm urea liquid received in this moist stage is then dried to some reliable, that has a nitrogen articles of about forty six%.

Constant level, move and differential pressure measurement Differential pressure transmitters with piezoresistive pressure sensors and welded metallic membrane or electronic dp or diaphragm seal is utilized generally in the process industry.

With its patented dual diaphragm design and style, Wika's Diaphragm Monitoring Process alerts operators immediately In the event the diaphragm in the seal assembly fails, assisting avert contamination of the method media and unscheduled downtime.

Liquid-Crammed gauges decrease needle flutter and เพรสเชอร์เกจ วัดแรงดันน้ำ offer extra balance with just a nominal lower in General precision.

Mounting by way of a versatile capillary for instruments mounted in a distant place in configurations involving Excessive temperatures or other harsh disorders

ส่วนที่ต้องสัมผัสสารเคมี น้ำเสียเคมี หรือ ของเหลวอื่นๆ ต้องทนกับสารเคมีนั้นๆ ได้ดีครับ อย่างน้อยต้องเลือก B ขึ้นไปครับ ลองคิดดูนะครับว่าหาก เราเลือกวัสดุต่างๆ ของปั๊มผิดอะไร จะเกิดขึ้นได้บ้าง ปั๊มต้องสูบของสารเคมีนั้น เรื่อยๆ มีโอกาสทำให้ ตัวปั๊มเสียหาย แผ่นไดอะแฟรมขาด ลูกบอลพัง ปั๊มไม่ขึ้น ต้องเปลี่ยนอะไหล่ หรือ แปปเดียวต้องเปลี่ยนปั๊มใหม่ ไม่คุ้มแน่ๆ ครับ
