MUTI-FUCTIONAL PRECISION DIGITAL MANOMETER
Overview
JC-YBS-DT smart precision digital pressure gauge is a portable high precision instrument form our company.This instrument using high quality components and automation testing technology,made of multi-CPU adjuvant treatment, it ensure the high degree of precision and reliability,with small siza,light weight,AC-DC power supply.This instrument has six and a half of the digital multimeter and the DC input and output functions of source,including the different range measurement and output of voltage and current;with pressure measurement function.
This instrument adoption of international temperature scale,to measure B,F,J,K,N,R,S,T eight thermocouples’ potential and temperature,it can simulate output the corresponding temperature and electric potential.It can measuring and simulation output of 4~20mA,0~10mAcurrent output pressure transmitter or 0~10V,0~5V voltage output pressure pressure transmitter,it can measuring the cold junction temperature of the instrument itself and automatic cold junction compensation.
This instrument can be used as a instrument with high precision measurement and calibration, with the functions of potentiometer,precision millivoltmeter,precision ammeter,cold junction thermometer and other equioment,and thermocouples check spresdsheet.It can be widely used in petroleum,chemical,metallurgy,electric power,measurement,automation and other mining sector and scientific research institutions.

Technique Data
1. Pressure
It depends on the precision of the pressure module. Because basic communication command is
compatible with modules of foreign famous brand, our company’s modules or imported modules can be used when main engine doesn’t lead in extra errors.
Pressure modules of our company are divided into gauge pressure, differential pressure, absolute
pressure, whose main range is:
1> Gauge pressure: -100kPa~1KPa~100MPa
2> Differential pressure:-100kPa~1kPa~1MPa
3> Absolute pressure: (0~110)kPa
For pressure module selection method, pls refer to P2
2. Voltage
Measurement:0-30V, 0-5V, accuracy: ±(0.001% RD+0.005% F·S), input resistance: >5 MΩ.
Output:0-15V, accuracy: ±(0.001% RD+0.005% F·S), output resistance< 1Ω.
3. Current
Measurement: 0-30mA, accuracy: ±(0.001% RD+0.005% F·S), input resistance: >5 MΩ(additionally adding fuse resistance)
Output:0~30mA, accuracy: ±(0.001% RD+0.005% F·S)
4. Thermocouple temperature indication
Model | Measurement range | Indication Precision % F·S(warranty of temperature range °C) |
K | -270~1360 | ±(0.05% RD+0.005% F·S)(-150~1360) |
N | -270~1280 | ±(0.05% RD+0.005% F·S)(-150~1360)(-100~1280) |
R | -50~1760 | ±(0.05% RD+0.005% F·S)(50~1760) |
S | -50~1760 | ±(0.05% RD+0.005% F·S)(50~1760) |
T | -270~400 | ±(0.05% RD+0.005% F·S)(-100~400) |
B | 50~1800 | ±(0.05% RD+0.005% F·S)(500~1800) |
E | -170~1000 | ±(0.05% RD+0.005% F·S)(-150~1000) |
J | -210~1200 | ±(0.05% RD+0.005% F·S)(-150~1200) |
Remark: To full range of indication precision, the temperature range in the column of indication
precision means warranty of precision measurement range, the actual precision has to put
measured thermocouple precision into consideration.
