PT190/PT192/PT193 safety relay high-temperature melt pressure sensor (transmitter) is a precise measurement equipment, using TI series of high-performance digital chip, circuit design based on SIL2, PL'C' safety performance standards, this series of products compared to other conventional high-temperature melt pressure sensor more than a relay alarm function, the function of the safety relay to play the role of alarm, by receiving electrical signals from the sensor, based on pre-set conditions to determine the trigger circuit to make the relay contact state changes, output a specific type of electrical signal warning equipment to ensure that the extrusion equipment and the start or stop. Alarm function, through the reception of electrical signals from the sensor, according to the preset conditions for judgment, trigger circuit to make the relay contact state change, output a specific type of electrical signal warning equipment start or stop, so as to ensure the safety of extrusion equipment and production line, effectively reduce the pressure overload damage to equipment and unpredictable personal safety accidents. This series of products is suitable for precision process control of extrusion equipment, production lines and so on.

Application：
PT190/PT192/PT193 Safety Relay Type High Temperature Melt Pressure Sensors (Transmitters) are products designed for pressure monitoring of liquids, gases, or pasty substances at elevated temperatures, which must be in a liquid, gaseous, or viscous flow state, with pressures not exceeding the upper limit of the measurement range in normal use, and with transient pressures not exceeding 150% of the upper limit of the measurement range (based on diaphragm surface). Any use outside of the above application ranges is non-compliant.
High-temperature melt pressure sensors are widely used in the petrochemical industry, they are mainly used to measure and control the pressure of high-temperature melts, fluids and gases, for example, in the production of chemical fibers, in the production of polyester rubber, in the processing of plastics and rubbers, in the manufacture of nonwovens and non-woven materials, in the production of packaging materials for construction, and other such application scenarios, it is required to use the High-temperature melt pressure sensors are used to control and regulate the pressure during the production process, ensuring a stable melt output and the efficiency of the product as well as the quality of the final output. At the same time, high-temperature melt pressure sensor can also be used in water conservancy and hydropower, railroad transportation, electric power, ships, machine tools and other fields, they play a key role in their respective applications.
All in all, high-temperature melt pressure sensors not only improve production efficiency and product quality, but also help reduce production costs and protect the environment and personnel safety. As technology continues to advance, the performance and application range of these sensors is expected to expand.
