I. Purpose

The wireless transmission technology of the W660 wireless large-screen smelting temperature measuring instrument synchronously and precisely transmits the temperature value measured by the hand-held temperature measuring instrument to the wall-mounted large-screen display through wireless transmission technology, eliminating the restraint of the connection line of the wall-mounted large-screen temperature measuring instrument, and further improving the anti-interference ability of the instrument. W660T is an improved type of W660, which is equipped with the T4 series rapid couple head, with more stable performance, and the couple head can be used multiple times. This instrument, when matched with the corresponding thermocouple, can perform precise and rapid temperature measurement in various occasions.

II. Characteristics

The W660 wireless large-screen smelting temperature measuring instrument has both the flexibility of the hand-held temperature measuring instrument and the long-distance visibility of the wall-mounted large-screen instrument (using a 5-inch digital tube display: character height 128mm). It eliminates the restraint of the connection line between the test gun and the large-screen display. This instrument is composed of a hand-held smelting temperature measuring instrument with wireless transmission function and a large-screen display with wireless receiving function (using 5-inch digital tube display: character height 128mm). It has the functions of synchronously lighting indication when the temperature measurement is finished, electric bell ring tone prompt, and automatically holding the measured value. It has alarm functions such as open circuit, overrange, and power supply undervoltage. This instrument uses original imported professional data transmission modules to ensure the high reliability of the wireless transmission of measurement data. This instrument can be equipped with 5 types of thermocouples. Due to the adoption of the latest anti-interference measures, this instrument has extremely good anti-interference ability. When the intermediate frequency furnace is powered on for smelting, it can perform temperature measurement in the furnace without power off. This instrument can store 1000 sets of historical data and can be optionally equipped with a printer. W660 has the function of communicating with a computer, and you can conveniently query and manage historical data on the computer.
