Miniature Pressure Transmitters are series of pressure measuring devices featuring a exclusively stainless steel made sleeve as electronic housing. As the idea of design aims to miniaturize pressure measuring instruments, the products have significant reduction in size and weight comparing to pressure transmitters with conventional terminal box. Such compact pressure transmitters could be especially competitive for integration on small machines or systems as well as constrained mounting space in all sorts of industrial process. Beside the key advantage of flexibility, their competent performance at a moderate cost even in demanding environments enable miniature transmitters a preferable solution for mass applications in budget-conscious projects.
External structure of a standard Wangyuan WP401B miniature pressure transmitter is composed of a cylindrical electronic housing, top DIN connector at the top and lower wetted part. The Hirschmann DIN43650 L-connector can offer a standardized, rapid and secure electrical wiring to supply the mini transmitter. Column case made of all SS304/316L is robust and endurable against extreme conditions.
Basic Wangyuan mini pressure transmitter could have multiple variants to adapt operating conditions and meet additional requirements:
For processes operates with extremely hot medium, high temperature transmitter can utilize radiation fins upon wetted part to dissipate heat before transferred to circuit and causes damage. Flat diaphragm of wetted structure facilitates smooth contact and elimination of cleaning blind spots. Tri-clamp and flange are usually applied as hygienic process connection. Such sanitary miniature transmitter is favoured for small equipment in food & beverage and pharmaceutical sectors. Instrument miniaturization also applies to differential pressure transmitter. Cylindrical case can be integrated with 2-pressure ports block, forming a T-shaped compact DP transmitter. Back to gauge pressure type, micro pressure transmitter reduces sleeve height to further compress product dimension for maximization of flexibility.
Key parameters of miniature transmitter dimension have all kinds of customer-specific options ensuring smooth integration with chain of process measurement and required functions. Compatibility of wetted part for medium is of great importance. Wide range of excellent materials can be chosen from SS304/316, PVDF, ceramic, or even a diaphragm seal fitting to assure corrosion-resistant performance. Small size 4-digit LED/LCD indicator is available upon cylindrical shell to provide easy display of on-site reading. Moreover, configuration of tilt LED indicator could offer additional relay alarm function. Electrical connection approach also has multiple choices, such as cable gland and submersible lead cable can enhance liquid-proof performance and bring own certain length of cable.
