In industries such as food, beverage, medicine, and biotechnology that require strict hygiene standards, the accuracy of temperature measurement and control is directly related to product quality and production safety. As a key equipment in this field, sanitary temperature transmitters have become a solution for industrial temperature measurement due to their functional advantages and design features.

1、 Core function: Accurate temperature measurement and signal conversion

The sanitary temperature transmitter adopts high-precision platinum thermistor (such asPt100）As a sensitive component, real-time acquisition and conversion of temperature signals are achieved through integrated module design. withW210TheHTM708Taking the model as an example, it supports-196℃to500℃Wide temperature range measurement with accuracy up to±0.15℃（ALevel), covering the needs of scenarios such as food processing and pharmaceutical sterilization. The device converts temperature signals into standard signals through built-in amplification circuits4-20mACurrent signal or0-10VDCVoltage signal, compatiblePLCIndustrial control systems such as recorders enable remote data transmission and automated control.

2、 Design advantage: combining hygiene and usability

Full hygiene grade structural design
The main body of the equipment adopts316LStainless steel material, smooth finish of the liquid receiving partRa<0.8No hygiene blind spots, in compliance withEHEDGTheFDAandGMPStandard. For example, the microphone sensorMTM4865The model is equipped with a fully stainless steel sealing structure andIP67Protection level, ensuring inCIP(In situ cleaning) andSIPThere is no residue during the in-situ sterilization process, reducing the risk of cross contamination.

Modularity and flexibility
Supports various process connection methods such as chuck, flange, thread, etc. Users can customize the probe insertion depth（10mm-2000mm）Compared to outer diameter（Φ4mm-Φ100mm）. Nanjing Hangjia Electronics'HTM708Model provided1.5Inch or2Installation options for inch chuck, and support electrical connection methods such as direct cable output and aviation plug, adapting to different on-site needs.

Multi signal output and display
Equipment optionalLCDBacklight display module, supporting4-20mATheModbus-RTU/RS485Waiting for digital communication protocols. For example,LG200-FRFThe integrated sanitary temperature transmitter not only provides analog signal output, but also integrates on-site display function, allowing for free adjustment of display angle and improving operational convenience.

3、 Industry application: covering temperature measurement needs throughout the entire process

Food and Beverage Industry
InUHT(Ultra high temperature treatment) equipmentCIP-SIPIn the system and drying equipment, temperature transmitters need to withstand the test of high temperature steam and chemical cleaning agents.W210The series achieves seamless docking through elastic rubber sealing technology, ensuring high-pressure sterilization（121℃Above) and acid cleaning（pH<2）Long term stable operation in the environment.

Pharmaceutical and Bioengineering
The precision requirements for temperature control are extremely high in scenarios such as pharmaceutical fermentation tanks and sterilization cabinets.HTM708The long-term stability of the model reaches±0.2%FS/Year, and supportHARTCommunication protocol enables real-time calibration and fault diagnosis of temperature parameters, reducing the risk of production interruption.

Chemical and Environmental Protection Fields
In the temperature measurement of corrosive media or high-temperature gases, the equipment needs to have anti-interference and corrosion resistance capabilities. For example, Meixu Measurement and ControlMX-WD-05The series adopts a compression spring anti vibration design, which is resistant to high pressure and earthquake, and is suitable for extreme working conditions such as petrochemicals and nuclear power.

4、 Technical highlight: Innovation drives industry upgrading

Fast response and high sensitivity
Metal protective tubeΦ4mmResponse time of the model<5In seconds,Φ12mmmodel<10Second, ensure real-time capture of data during transient temperature changes (such as sterilization kettle heating).

Intelligent protection mechanism
Built in overcurrent, voltage limiting, and reverse protection functions, such as Huayi AofengT1000ZCExplosion proof sanitary temperature transmitter can still operate stably in flammable and explosive environments, and meets the requirements of sanitary surface smoothness, reducing the difficulty of cleaning.

Long lifespan and low maintenance
The equipment undergoes strict aging tests on components, semi-finished products, and finished products, such asW210Series sensors with cold end temperature resistance250℃After long-term use, the accuracy deteriorates<0.1%Reduce downtime maintenance costs.
