SERVOPRO FID is a hydrogen flame ionization detector-based analyzer that ensures safe operation in cryogenic air separation plants by keeping total hydrocarbon (THC) content below combustible limits. SERvOPRO FID can also perform quality control on pure oxygen, nitrogen, argon, and air.
The SERVOPRO FID is a flame‑ionization detector (FID) analyser designed for safe operation of cryogenic air‑separation plants. It measures total hydrocarbon (THC) content in air, oxygen, nitrogen and ammonia streams, and includes flame‑out detection that automatically shuts off the fuel gas.
The analyser offers three measurement ranges (0‑10 ppm, 0‑100 ppm, 0‑1000 ppm) with an overload capability up to 10 000 ppm, digital communication via RS232 ASCII, optional Ethernet (TCP) and relay contacts, and a 4‑20 mA analog output. It complies with IEC 61010‑1, IEC 60664‑1, EU Low‑Voltage, EMC and WEEE directives and operates from 100‑120 V or 220‑240 V AC. This manual is written in Chinese.
| Analog output | 4‑20 mA isolated output |
|---|---|
| Serial communication | RS232 continuous ASCII (optional) |
| Ethernet interface | TCP/IP (optional) |
| Operating temperature | 5 °C to 40 °C |
| Relative humidity | 0‑95 % non‑condensing |
| Sample gas flow rate | 300 ml/min to 500 ml/min |
| Sample gas pressure | 5 psig to 15 psig |
If a flame‑out is detected, the system automatically cuts off the fuel‑gas supply.
The analyser provides RS232 ASCII output, optional Ethernet (TCP) and digital relay contacts.
The overload range can reach up to 10 000 ppm (19 %).
