Noise Sensor with 4-20mA Current Loop Output

The Noise Sensor range of noise monitors have current loop (4 to 20mA) outputs to link to your distributed control system or data acquisition system. These are ideal for typical DCS or SCADA systems, but work perfectly with any 4-20mA current loop interface.

Meeting the sound level meter standards to Type 1 or Type 2 and with an option for use in hazardous environments, the Noise Sensors are ideal for most environmental noise monitoring applications.

Indoor or Outdoor

Both the NoiseSensor and the NoiseSensor^LITE are protected against rain, snow and dust. They can be used for indoor or outdoor noise monitoring. The MK440 LITE version is physically smaller, so more suited for some indoor installations, while the MK427 has more weather protection for extreme environments.

Hazardous or Explosive Atmospheres

The MK440 NoiseSensor^LITE has approval for use in potentially hazardous environments. It is certified for use in Class 1 Division 2 hazardous environments, such as mines, gas pumps, gas stations, processing plants and food manufacturing plant.
