Yuyao changjiang temperature meter factory
Ⅱ、Technical standard
2.1、Input and range（one meter can be compatible）：
①Thermocouple：K（-50～1300℃）、S（-50～+1700℃）、T（-200～+350℃）、E（0～800℃）、
J（0～1000℃）、B（0～1800℃）、N（0～1300℃）、WRe(0～2300 )℃
②Thermal resistancer：CU50（-50～150℃）、PT100（-20～600℃）；
③Linearity voltage：0～5V、1～5V、0～1V、0～100mV、0～20mV；
④Linearity current（with diffluent resistance）：0～10mA、0～20mA、4～20mA
⑤Linearity input: -1999~+9999 (user freely setting)
2.2、precision：
①Input by thermal resistance , linearity voltage and linearity current 0.5F·S+1
②Thermocouple input adopt copper resistance or freezing compensate cold end 0.5 F·S +1；
③Although the meter can measure B、S、WRE during the temperature 0～600 ,its measurement℃
could not reach 0.5 class；
④differentiate rate：1、0.1；
2.3、response time: ≤0.5s (filter parameter sets 0)
2.4、Adjusting mode：
①ON/OFF control method（Return difference can be adjusted）；
②Common PID control（with the parameter of self-setting function）
③Intelligence adjustment(including vague PID adjustment and advanced control algorithm with the
parameter of self-setting function)；
2.5、Output specification：it make out directly output parameter modularity or without modularity：
①The switch of relay contact point output（open+ closed）：250VAC/7A or 30VDC/10A；
②SSR voltage:12VDC/30mA(apply for driving SSR relay)；
③Contact point output with controllable silicon: can contact 5～500A two directions controllable
silicon;2 separate directions controllable silicon opposite direction parallel.
④Liner electric current output：initial current and terminal current value can be defined when the
output is 0～24mA（voltage range 11～23VDC）；
2.6、Communication：
Support RS485communication mode，adopt AIBUS communication agreement，and baud rate
support the below selection ：1200bps、4800bps、7200bps、9600bps
2.7、Alarm:
Support two passive contact output，relay contact 250VAC/7A；It has four methods including
upper limit, lower limit, positive deviation ,negative deviation .It can output 2 ways at most；
2.8、Tolerance for pressure when it is segregated：Between electric power ,relay’s contact and signal’s end ,do
2000V pressure tolerance test 1s,there is no abnormal phenomenon;
2.9、Movement with hand: Automatic /Manual；
