Product Details

Temperature and humidity sensor introduction

Mine temperature and humidity sensor is controlled by single chip microcomputer intelligent composite sensor. The sensor using the Ann circuit design, suitable for the coal mine or environment with explosion danger on the ground, to mine coal face or a mining area, in the return air temperature and humidity for continuous detection.The sensor adopts imported sensors, has a high detection sensitivity, good stability, wide measurement range, good compatibility and nonlinear correction, liquid crystal display, etc.

Temperature and humidity sensor parameter

Measuring range:

Temperature: 0 ~ 100 ℃, humidity: 0 ~ 100% RH.

The basic error

a) shows the error of ≤ ± 2.5% (FS); humidity ≤ ± 8 (FS).

b)output error ≤ ± 2.5% (FS); humidity ≤ ± 8 (FS)

Major electrical performance Operating voltage: 9V ~ 24V DC;

Working current: ≤ 100mA DC.

Maximum transmission distance: sensor and associated equipment of maximum transmission distance is 2 km (need MHYVR type mining communications cables, cross section is not less than 1.5 was, R = 12.8 Ω/km, 0.06 uF/km or less C, H, 800 or less uh/km, and the display of the device context value or output signal conversion for temperature and humidity value shall comply with the terms of 4.4.2).

Output signal system (two formats available remote transmitter switch):

Frequency signal types: (constant-current pulse) 200 ~ 1000Hz; pulse width ≥ 0.3ms, "1" is not less than 4mA, "0" is not greater than +0.2 mA. (Load resistance 0 ~ 600Ω)

Digital-signal-type: (constant-current pulse) 1200bps; "1" is not less than 4mA, "0" is not greater than +0.2 mA. (Load resistance 0 ~ 600Ω)
