YBS-S100 Pressure Transmitter Calibration Method，Precise Measurement Starts Here

Mastering the YBS-S100 pressure transmitter calibration method is the key to ensuring precise measurement with diffused silicon sensors。This article is intended for users of various pressure transmitter models such as LD-LD183、PS-201，and provides a detailed introduction to calibration steps and techniques，helping you achieve reliable monitoring of liquid/gas pressure。From alarm control to remote signal commissioning，it makes industrial measurement more accurate and efficient。

I、Core Significance of Pressure Transmitter Calibration

In the field of industrial automation，the measurement accuracy of diffused silicon pressure transmitters such as YBS-S100 directly affects production safety and efficiency。The calibration process eliminates zero drift and span errors by adjusting the correspondence between the sensor output signal and the standard pressure value。Taking the PN-M2 model as an example，uncalibrated equipment may lead to a deviation of ±0.5%FS，while after standardized operation it can be controlled within ±0.1%FS。Calibration is not only a requirement of the ISO9001 quality management system，but also a key measure to prevent false triggering of the PS-201 alarm control system。

II、Detailed Standard Calibration Procedure（Taking YBS-S100 as an Example）

1. Preparation：After turning off the power，connect the standard pressure source，use a standard instrument with an accuracy 3 times higher than that of the transmitter（such as a 0.05 grade piston pressure gauge），and check the special interface compatibility of ET-A customized equipment
2. Zero Adjustment：Under normal pressure conditions，zero the corresponding value of the 4mA output via a HART communicator or local buttons，noting that the LD-LD183 model must keep the sensor installed vertically
3. Full-Span Calibration：Apply the rated pressure（such as the 10MPa range of the CEQ1300 model），adjust the 20mA output point，and for the PN-M2 model with remote transmission signal，check the RS485 output simultaneously
4. Midpoint Verification：Test the linearity at the 50% span point，and the MS-MS132 model requires the repeatability error of three cycle tests to be ≤0.05%

III、Special Calibration Points for Different Models

IV、Diagnosis and Handling of Calibration Failures

When nonlinear errors occur after calibration of the MBC-1 model，first check whether the diffused silicon diaphragm is contaminated（commonly seen in the measurement of viscous media）。For the vibration interference issue emphasized in the PCM-D installation instructions，the following solutions can be adopted：① Add a pulsation damper ② Switch to the CEQ-CEQ1300 high-frequency response version ③ Enable the digital filtering function on the software side。Data shows that 80% of YBS-S100 calibration abnormalities originate from oxidation of wiring terminals or power supply fluctuations。

V、Analysis of Differences in Industry Application Scenarios

• Petrochemical Industry：ET-A customized models require additional hydrogen sulfide protection calibration
• Pharmaceutical Industry：The MS-MS132 model requires a sanitary calibration process certified by 3A
• Water Treatment：The LD-LD183 model requires response time adjustment for sludge media

VI、Frequently Asked Questions（FAQ）

Q：The alarm point of the PS-201 model is frequently triggered falsely？
A：Check the pressure loading rate during calibration。Pressure shock caused by quick-opening valves may be misjudged as actual pressure。It is recommended to add a 0.5-second delay according to the HB-S manual。

Q：After calibration of the remote transmission signal type PN-M2，the on-site display is inconsistent？
A：This is a typical ground loop interference phenomenon，requiring：① Check the RS485 terminating resistor ② Use the CEQ1300 dedicated isolator ③ Include communication protocol verification during recalibration。
