HM70 Hygienic Flat - membrane Pressure Transducer

Description

HM70 hygienic flat - membrane pressure transducer adopts imported high – accuracy and high – stability pressure sensor set to the absolute pressure or the gauge pressure of the medium to be measured into 4 ~ 20mA, 1 ~ 5V / 0 ~ 5V standard electrical signal through high – reliability amplification circuit and precise temperature compensation. High – quality sensor, fully – enclosed welded encapsulated technology as well as improved assembling process ensure superior quality and best performance of this series of product.

Features of Product

☆ High stability and high sensitivity

☆ Lightning and radio frequency disturbance immunity

☆ Diversified signal output form and adjustable zero point and full scale

☆  Reverse pole protection and transient over – current and over – voltage protection☆ Fully made of stainless steel

☆ Clean flat type of isolating membrane

Application of Product

☆  Hygienic pressure pipelines  

☆  Food and beverage processing

☆  Medical and pharmaceutical

☆  Sewage treatment

☆  Viscous medium pressure measurement

Tips of Selection

  1. Correctly adopt sealing means to prevent the product stability from influencing due to installing stress when the flushed membrane product is installed on site.
  2. The medium to be measured shall be compatible with the material contacting with the product.
  3. The code E, an additional functional code for selection, and intrinsically safe explosion-proof Ex ia II CT5 must be power supplied via safety barrier.
  4. Please contact us in case of the other special requirements and clearly indicate them when placing an order.
