This document describes a intrinsically safe explosion-proof pressure transmitter for the semiconductor industry. It has high corrosion resistance and durability, and can be used in places where explosive gas exists. The transmitter has special connection and gas contact parts for the semiconductor.
The KJ96 is a 2‑wire intrinsically safe explosion‑proof pressure transmitter designed for hazardous Zone 0 environments. It uses a semiconductor evaporated (SS) sensor with a Co‑Ni alloy diaphragm for high corrosion resistance and durability, and complies with IEC Exia TC T4 safety standards.
The document provides general specifications, hazardous‑area classifications, wiring examples, dimensional data, and ordering options, including recommended safety barriers and connector types. It is intended for engineers and technicians who need to select, install, and maintain the transmitter in semiconductor and MEMS processing facilities. This manual is written in Japanese.
