How to Use the KY-2 Pressure Transmitter? Diffused Silicon Hirschmann Pressure Sensor Operation Manual
Added to Favorites:125

KY-2 Pressure Transmitter Operation Guide: A Full Process Analysis from Installation to Maintenance

As a representative product of diffused silicon Hirschmann pressure sensors, the KY-2 pressure transmitter is widely used in the field of industrial automation control. This article will introduce in detail the correct use of the KY-2 pressure transmitter, helping operators quickly master installation and commissioning, parameter settings, and daily maintenance essentials to ensure stable equipment operation. As a professional manufacturer, Xi'an Shenghongchuang Instrument Co., Ltd. provides high-quality pressure sensor solutions.


1. KY-2 Pressure Transmitter Installation Specifications

1.Installation location selection:

  • Avoid strong electromagnetic interference sources (such as frequency converters and high-power motors) within a range of 3 meters
  • The medium flow direction should be consistent with the arrow marking direction on the sensor
  • In vibration environments, shock-absorbing brackets must be installed

2.Key points for mechanical installation:

  1. When using the M20×1.5 standard threaded interface, it is recommended to use a red copper gasket for sealing
  2. For flange installation, ensure uniform force distribution, with torque controlled at 15-20N·m
  3. When installed vertically, the electrical interface should face downward to prevent condensation from accumulating

Similar to domestic general-purpose pressure transmitter PM320 water pressure oil pressure air pressure sensor, products using a 316L stainless steel isolation diaphragm structure perform particularly well in corrosive media environments such as chemical and petroleum industries.


2. Electrical Connection and Parameter Configuration

Hirschmann connector wiring specifications:

Pin NumberFunction DefinitionCable color
1Power Positive (+24VDC)Brown
2Signal output (4-20mA)Blue
3Power Negative/GNDBlack

Span calibration steps:

  1. Adjust the zero point through the ZERO potentiometer (no-load state)
  2. Apply full-scale pressure and calibrate using the SPAN potentiometer
  3. Repeat the cycle 3 times to verify that the linearity error is ≤0.25%


3. Daily Maintenance and Troubleshooting

Periodic maintenance items:

  • Check the aging condition of sealing components every month
  • Calibrate zero drift every quarter (allowable ±0.1%FS)
  • Carry out full-scale calibration every year

Common fault handling:

Fault SymptomsPossible CauseSolutions
Output Signal FluctuationPower Supply Interference/Poor GroundingInstall a signal isolator
Zero drift exceeds specificationDiaphragm stress relaxationRecalibrate or replace the sensing element

For working conditions requiring a higher medium temperature range (-40~+400℃), you may consider upgrading to the domestic general-purpose pressure transmitter PM320 series products.


4. Technical Advantages of Diffused Silicon Sensors

The core technical features adopted by KY-2 include:

  • Temperature compensation technology: error ≤±0.5% within the range of -20~+85℃
  • Overload-resistant design: 200% full-scale overpressure protection
  • Media compatibility: achieved through the combination of 316L stainless steel and fluororubber seals
