The best domestic logging devices
After many years of domestic use and verification of large cement plant, the best choice.
Jing Chuan MTT series of intelligent multi-channel temperature logging instrument
I. Overview
Jing Chuan MTT series of multi-channel temperature logging devices using a number of international advanced technology, with 100 ~ 240VAC wide range input switching power supply, input digital calibration and self-calibration techniques, measurement accuracy and stability, eliminating the measurement drift caused by drift error. meter using multiple protection and isolation design, anti-jamming performance, high reliability. meter all imported high-quality terminals, wiring easy, secure.
Jing Chuan MTT inspection channel number series of multi-channel temperature logging instrument can be arbitrarily set the standard specifications are 8, 16 and 32 three;. MTT-LCD instrument has 8 and 16 in two sizes; MTT- M instrument only eight polling channel.
Jing Chuan MTT series of multi-channel temperature logging instrument has multiple types input functions, each channel can be set to different input signal (thermocouple / RTD / Linear voltage / linear current / linear resistance) respectively, through the parameters, greatly reducing the backup The number of tables. scope is very wide, can be used with various types of sensors, transmitters used in conjunction to achieve the measurement of temperature, pressure, liquid level, capacity, power and other physical display, alarm control, data acquisition and recording.
Each channel has two independent alarm setpoints, parameters can be set through the alarm mode (upper and lower; lower ceiling; on the upper or lower limit)., Through two common alarm relay output which MTT-M instrument also can be Two alarm points per channel with independent alarm relay output.
Jing Chuan MTT series of multi-channel temperature logging instrument instrument optional communication module (RS232 / RS485), communication with the host computer, or via the RS232 interface mini-printers, timer / random print measurement data for each channel.
Jing Chuan MTT-LCD instrument uses 128 * 64 LCD, each screen can display 8-channel data.
Second, the technical specifications
Input Specifications
