By letter Amplification processing unit, and the A/D conversion, and then calculated directly by a microprocessor corresponding to the pressure, body temperature Concentration of methane fraction represented and displayed on the monitor, enabling the optical interference of methane detector test. Block diagram of Figure 1 Calibrator work Calibrator can be divided into direct and non-direct reading reading type. a) Direct-reading type Calibrator principle is the collected pressure and temperature values calculated directly corresponding to the pressure, Methane concentration test point temperature value expressed in volume fraction, and displayed on the display. b) Non-Direct-reading type Calibrator principle is to only collect pressure, according to test ambient temperature, and then calculate Corresponding to the pressure, temperature test point concentration of methane by volume expressed as a fraction.3 metering performance requirements3.1 Indication error Calibrator to represent the volume fraction of the measurement range and the maximum permissible error in Table 1, the Calibrator to measure pressure expressed The scope and amount of the maximum permissible error in Table 2. Table 1 Calibrator to represent the volume fraction of the measurement range and the maximum permissible error Measurement range /% CH4 0 ~ 10 0 ~ 100 The maximum permissible error /% CH4 ± 0.016 ± 0.12 Table 2 indicates Calibrator pressure measurement range and the maximum permissible error With respect to the concentration of methane 0 ~ 10% CH4 0 ~ 100% CH4 Measurement range/kPa 0 ~ 8 0 ~ 60 The maximum permissible error/kPa ± 0.008 ± 0.06 ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of JJG 1040-2008_English be delivered?Answer: Upon your order, we will start to translate JJG 1040-2008_English as soon as possible, and keep you informed of the progress.
