As a core component in the field of industrial automation, the dimensional parameters of the SMP-X pressure transmitter directly affect equipment installation and system integration efficiency. This article will provide a detailed interpretation of the meanings of various key parameters in the dimensional drawing of the diffused silicon Hirschmann pressure sensor, helping operators quickly grasp the key installation and positioning points of models such as JP-40C, WY-131, and solve common on-site dimensional matching problems.

Analysis of Core Parameters in the Dimensional Drawing of the Diffused Silicon Hirschmann Pressure Sensor

When installing JP-40C or DS-DS3000 pressure transmitters at industrial sites, operators often cause sealing failure by neglecting key dimensions such as the outer diameter of the flange and the depth of the threaded connection. Taking the SMP-X model as an example, its dimensional drawing includes three core parameter groups: process connection dimensions (including the tapping depth of the G1/2" thread of 12±0.5mm), overall housing height (98mm for the standard type, with an additional 25mm for the remote signal type), and electrical interface position (the center distance from the M20×1.5 cable connector to the flange face is 62mm). These parameters are directly related to practical issues such as whether the equipment can match the pipeline flange and whether the opening position of the electrical cabinet is accurate.

Typical Installation Misunderstandings and Correction Solutions

When a chemical plant installed the WY-131 pressure transmitter, it did not verify the concentricity tolerance between the process connection thread of the diffused silicon sensor and the pipeline flange (which should be ≤0.1mm), resulting in medium leakage. By comparing the dimensional specifications of the PT124B-211 model, it was found that the flatness requirement of its flange mounting surface must reach Ra3.2μm, and the pitch circle diameter error of the bolt hole distribution must be controlled within ±0.3mm. It is recommended that operators use laser centering instruments for auxiliary positioning when installing the DS-D model, and refer to the 304 stainless steel flange standard of our Domestic Temperature Transmitter RS-WB200B Integrated Industrial Digital Display Temperature Transmitter for preload testing.

Dimensional Adaptation Solutions Under Special Working Conditions

For installation of the CYG1003 pressure transmitter in a compressor room with limited space, a short-neck flange variant (with total height reduced by 30%) can be used. When handling corrosive media, the 316L stainless steel flange of the WW-131 model needs to be paired with a thickened sealing gasket (thickness ≥3mm), which is consistent with the anti-corrosion design concept of the Domestic Temperature Transmitter RS-WB200B Integrated Industrial Digital Display Temperature Transmitter. In a vibration environment, it is recommended to select the PT124B-211 model with an anti-vibration bracket, whose housing rib thickness reaches 5mm, far exceeding the requirements of the ISO 10816 vibration standard.
