Description of structural elements and means of explosion protection
7.1. The positioning monitor consists of a casing inside which, depending on the type and
construction, are fitted mechanical switches, inductive gauges, reed switches and transmitters.
The valve positioning monitor is manufactured in a casing with "d" explosion protection. The casing
may be manufactured from stainless steel or from aluminium. The casing is closed by means of a
threaded dome-shaped cover and has two threaded holes for the connection of cable inputs. The
cover is secured to the main body with four M5 x 0.8 stainless steel bolts.
Installed inside the casing are an indicator, a Klemm brake, certified switches and gauges. The
indicator is installed in the upper portion of the casing and offers a visual indication of the position of
the shaft. Connection of the leads is effected through the Klemm brake that is mounted in the casing.
The valve positioning monitors has a degree of protection conforming to IP67 as per GOST14254-96.
7.2. Explosion protection of the AQ and SRX valve positioning monitor is by means of an
intrinsically safe electric circuit of level "ia" that is maintained by the following means.
7.2.1. The electric load on active and passive elements in intrinsically safe circuits and explosion
protection elements must not exceed 2/3 of nominal readings.
7.2.2. Leakage paths, electrical clearances and dielectric strength and the electrical parameters of
contact joints meet the requirements of GOST R MEK 60079-11-2010.
7.2.3. The electrical parameters of intrinsically safe circuits meet the requirements for this sub-set of
electrical equipment. Capacitance and inductance do not exceed the regulated requirements of
GOST R MEK 60079-11-2010.
7.3. Explosion protection of the AQ and SRX valve positioning monitor is by means of an
intrinsically safe explosion-resistant casing "d" that is maintained by the following means.
7.3.1. Electrical parts are fitted inside an explosion-resistant sleeve which will withstand the
pressure from an explosion and inhibit its transmission into the surrounding medium.
7.3.2. The assembly of individual parts is by means of sealing gaskets.
