Sound level meter Sh3-M

Also this device can be called: Sh3M, Sh3 M.

 

Sh3-M sound level meter is designed to measure the levels of stationary acoustic noise in the air. The principle of operation is to convert the microphone of an acoustic signal to an electrical.

 

Scope of sound level meters Sh3-M: implementation research in the field of noise, while developing noise drowns devices when checking OTC plants finished products and components to be exposed to their noise, industrial and sanitary doctor of SES, health centers and doctors LSG, workers labor protection when checking conformity of production, transport and household noises relevant standards.

 

Specifications Sh3-M:

 

Measurement dynamic range - from 25 dB to 130 dB.

Three switching frequency characteristics of the "A", "B" and "C" in the range from 50 Hz to 10 000 Hz.

 

Change detection limits made in steps of 10 dB each, with an overlap between adjacent 5 dB in the direction of smaller limit.

Scale indicating instrument is calibrated in decibels between -5 dB to +10 dB.

Graduation - 1 dB.

 

Switching characteristics of the sound level meter indicator - "fast", "slow".

Calibration of sound level meter - electric, from a built in sound level meter generator.

Supply sound level meter - three dry anode batteries 49-SAMTSG -102 h and two elements 1.58-SNMTS-17h.

 

Overall size of the sound level meter - 251×161×210 mm.

Weight sound level meter Sh3-M - no more than 5 kg.

 

Sh3-M is a microphone that is connected to a voltmeter, calibrated in decibels. Because the electric signal output from the microphone is proportional to the original audio signal, the gain of the sound pressure level acting on the microphone diaphragm, causes a corresponding increase in the voltage of the electric power input to the voltmeter, which is displayed by the display device, calibrated in decibels.

 

Operating conditions Sh3-M:

 

Ambient temperature - from +10° C to +36° C.

Relative humidity - 80%.

 

No mechanical vibrations and powerful fixed and variable fields.

Horizontal position.

Powered by dry cell battery with a voltage of not less than 47 (anode) and 1.4 V (intensity).
