The Monitran MTN/M2200 is a general-purpose constant current accelerometer with an isolated AC output, certified to ATEX and IECEx Group I for intrinsic safety (Ex ia I Ma), with a standard sensitivity of 100 mV/g ±10% at 80 Hz and a response of 2 Hz to 10 kHz ±5%. The datasheets cite applications in general industry, compressors and pumps, oil and petrochemicals, and mining.
Stainless steel body with insulated base and isolated internal electronics to minimize noise and provide greater polarization voltage stability; IP67 rated. Four variants: top entry (M2200I with 2-pin MS connector, M2200IC with integrated ETFE cable) and side entry (M2200IS with connector, M2200ISC with cable) with ¼"-28 UNF, M6, or M8 mounting bolts. Guemisa is an official distributor of Monitran in Spain.

Intrinsically safe for mining (Group I, protection level Ma). Hover or click on each part of the marking to see what it means.
For what environments is the Monitran MTN/M2200 certified?
For Group I (mining), with Ex ia I Ma marking, ambient temperature from −55 °C to +115 °C and BAS02ATEX0245X and IECEx BAS 08.0013X certificates.
Do you need an intrinsically safe barrier?
Yes. It connects through a barrier. The datasheets cite the MTL7728+ (BAS01ATEX7217) and the P&F Z728 (BAS01ATEX7005), or any other barrier conforming to note 5 of drawing ATX037. Entity parameters: Ui = 28 V, Ii = 93 mA, Pi = 0.65 W.
Is it suitable for surface industry (Group II)?
No. The technical data sheets certify the M2200 only for Group I (Ex ia I Ma) and do not indicate Group II certification.

Do not install in an atmosphere with high-speed airborne dust.
M2200ISC: The sheet warns that Ci and Li were previously lower and that the installer should take into account the increase in internal capacitance and inductance (the note on the sheet refers to Group II).
M2200IC: dynamic range ±80 g (the sheets of the other variants do not indicate this).
The Ci and Li parameters refer to the certificate; the sheets do not give their value.
