Melt Pressure & Temperature Sensor
The innovative resin pressure sensor that measurespressure optically.

Durability is improvedby the sapphire single
crystal diaphragm!

Achieves high-pressure measurementof ±0.5% F.S. at 400°C!

High-precision pressure measurement athigh temperatures with an optical system!

•Compatible with high temperatures(400°C)•

Simultaneous measurement ofpressure and temperatureThis is an optical sensor that does not use
semiconductor elements in the detection unit, sohigh temperature measurement (±0.5% F.S. at400°C) is possible.

Simultaneous measurement of pressure andtemperature with an optical pressure sensor and abuilt-in thermocouple.

•By adopting a sapphire diaphragm,
durability performance is improved
compared to conventional products•Compared to metal diaphragms, it has 4.5 times
the tensile strength and 10 times
the wear resistance.

No enclosed liquid structure
Achieves high accuracy ±0.25% F.S. (at 150 to300°C) with a safe and secure structure that uses
an optical system and does not use an "enclosedliquid" to transmit pressure change.

A gap is provided in the sapphire element, and the gap distance that changes depending on
the pressure applied to the diaphragm is directly measured by using the white interference
method. Simultaneous temperature measurement is also possible with a thermocouple.
