ATEX approved Mechanical HandTachometer of RHEINTACHO gets
Class I approval for Zone 1 Mining
Applications
O
ur proven ATEX version of the mechanical
hand-Tachometer has moved on to the next
level of application – Class I. RHEINTACHO
UK successfully took on the challenge of
getting this approval. This enables many new additional
applications in ATEX class Zone 1 and 2 areas. The
certification is valid from 18 November 2015.
New ATEX
Class I approved
mechanical handtachometer HTM
Mindful of the need to operate tachometers in areas
where there is a risk of explosive atmospheres due to
either dust particles or gas, our engineers have carried
out modifications to enable this version to be certified for
use in ATEX Zones 1 and 2 for use in all gas groups with a
temperature class of T4 also being without compromising
the capability of the original design. This certificate
approves the use in underground mining applications.
The use is intended for short term observation and
measurement, not for continuous operation.
The ATEX HTM measures rotational or linear speed using
the special contact adaptors supplied. With no need for
batteries, it has the safety and flexibility to satisfy the
most demanding requirements for maintenance and
calibration. The reference numbers: EX II 2 G D C II C T4,
I M2 c
Easily identified by its yellow ergonomically designed
casing, the ATEX HTM is available in four models and is
supplied in a hard plastic carrying case complete with a
set of adaptors:
HTM-100M (A3-5100): 10 - 10,000 rpm / 1 – 1,000 m/min
HTM-500M (A3-5500): 30 - 50,000 rpm / 3 – 5,000 m/min
HTM-100F (A3-5110): 10 - 10,000 rpm / 5 – 5,000 ft/min
HTM-500F (A3-5510): 30 - 50,000 rpm / 15 - 25,000 ft/min
