Tevel presents new measuring process units




07/03/2023

Measuring process unit type MPU-XX is stationary device for continuous measurement and
detection the explosive gases, toxic gases, oxygen, temperature, humidity, air flow, pressure, etc.
in a mining application. It is used to ensure safety, prevent explosion, and to measure and monitor
the other important parameters in a mining application.

The robust, lightweight and compact constructed measuring device is designed in intrinsic safety Ex
ia protection according to standards EN 60079-0:2018, EN 60079-11:2012, EN 60079-28:2015 (with
SBH) and EN 50303:2000.
On the device can be optionally added a certified intrinsically safe Signal Flash Light with Horn SBH
ia/MPS, certificate FTZU 11 ATEX 0186 (I M1 Ex ia op is I Ma).
The device is intended for underground mining application as well as surface mining application
where may be a potential risk of fire and/or combustible dust is present. It’s enclosure is made of 2
mm thick stainless steel. The housing cover is sealed with flat rubber washer which assure high
ingress protection. The connection of the device can be made by 16 pole plug-in female connector
for fast and easy device connection or disconnection.

Depending on the measuring principle, type of measuring gas and other parameters, 12 versions of
device is available:
  • Explosive gas methane (CH4) – pellistor
  • Explosive gas methane (CH4) – IR
  • Suffocating gas carbon dioxide (CO2) – IR
  • Toxic gas carbon monoxide (CO) – electrochemical
  • Oxygen (O2) – electrochemical
  • Toxic gas hydrogen sulfide (H2S) – electrochemical
  • Explosive gas hydrogen (H2) – electrochemical
  • Pressure (p) – piezoresistive
  • Differential pressure (Δp) – piezoresistive
  • Temperature (T) – silicone band gap
  • Relative humidity (Rh) – capacitive
  • Air flow rate (v) – thermal
Tevel has specialized in finding innovative solutions for mining, industry, engineering, public facilities
and households since 1990. We provide complete solutions for measurements, control and
automation in hazardous areas (Ex) that enable safe workplaces.
