Product description:

An overview,
XM series digital display apparatus according to the national standard "industrial process measurement and control system with digital indicator, production, and adopted a novel, unique circuit design principle, the structure of the original form.Then the structure and the circuit is very simple, so high reliability, good shock resistance, convenient in operation and maintenance.
This instrument is 0 ~ 10 ma, or 4 ~ 20 ma constant-current output function, profile control system with actuator, or rection of computer automatic control system does not need to match again transmitter, provides convenience for industrial process parameter control, have two type at the same time, three time proportion PID regulating function.
This instrument is suitable for a variety of industrial process parameters measurement and control system.Can be used with the following sensors, transmitter or accept the following signal.Directly with digital display measured quantities.
A, flame state, thermocouple, or radiation.
B, heat resistance sensor of resistance change,
C, hole pressure transmitter or result in a change to dc sensing transducer;
D, resistance far eastone pressure gauge;
E, standardized analog dc signal (Ⅱ, Ⅲ) or other dc signal.
Second, the main technical indicators
1, use way, plate mounted.(horizontal type, vertical type and square three)
2, indicating method: 3 1/2 level LED digital tube display, the largest reading 1999.
See table 3, model specifications: specifications;Measuring range to see the table below.
4, the basic error: plus or minus 0.5% f. S + 1. (f. S to show the range)
5, resolution: | 200 | below: 0.1 ℃ above 200 | | 1 ℃.(the other physical quantities for the bottom one word)
6, the most great momentum: less than two resolution value amount (wave depression in terms of volatility from median size).
7, zero drift, zero drift in one hour less than one 5 of the basic error.
After 8, continuous work, the still meets the requirements of this error.
9, exterior size: 160 * 80 * 175 (mm).Square table is 96 * 96 * 96 (mm).
10, the size of the hole: horizontal type 152 * 76 (mm).Vertical is 76 * 152 (mm).Square table is 90 * 90 (mm).
11, work power: 220 v.50 hz plus or minus 10%.
12, weight: 1.25 kg.
13, working environment: temperature for - 10 ~ 50 ℃, relative humidity of not more than plus or minus 90%
14, a type of control;Set range full range;To control error is less than + / - 0.5% f. S + 1 word.Contact output capacity: 220 v, 3 a.Non-inductive (communication load).
15, constant current output: load capacity 0 ~ 10 ma of 0 ~ 1.5 k omega.4 ~ 20 ma, 0 ~ 450 ohms, the output precision is less than + / - 0.5% f. S.
