The Dovelet TP-1.1A is a non‑heated, low‑power methane gas sensor with detailed specifications, test data, and usage guidelines.
The TP-1.1A sensor from Dovelet is a non‑heated, low‑power device that offers high sensitivity to methane and liquefied petroleum gas. Its low power consumption enables applications such as coal‑mine gas monitoring, industrial methane detection, domestic gas leak alarms, vehicle safety monitoring, and portable gas detectors.
The manual provides the sensor’s electrical characteristics, mechanical strength limits, temperature and humidity performance, and detailed test procedures. It also describes the recommended test circuit, initial power‑up behavior, and methods to restore sensitivity after oil contamination. This manual is written in Chinese.
