1 PRODUCT DESCRIPTION
The 2600 series valve position / control monitor
provides two methods of end of travel indication
by the means of mechanical switches, inductive
proximity sensors or proximity switches and an
external visual indicator.
For applications that require position feed
back, ancillary components such as a 4-20mA
current signal transmitter or a resistive signal
feed back can be installed.
The 2600 series enclosure is available in two
materials; cast aluminum or 316 stainless
steel. The enclosure construction comprises
of a housing with a screwed cover.
The housing has the option of up to three cable
entries for connection to an external power
source via appropriate ATEX and IECEx certified
cable glands:
M20 x 1.5p, M25 x 1.5p, ½” - 14 NPT or
¾” - 14NPT.
Note: Before installation of this product, please
ensure that the product and its certification is suitable
for the intended application. This product uses various
O-ring material and an Eastar copolyester visual
indicator as standard.
If the equipment is likely to come into contact
with aggressive substances, then it is the
responsibility of the user to take suitable
precautions that prevent it from being
adversely affected, thus ensuring that the type
of protection provided by the equipment is not
compromised.
Installation of any cable entry devices,
conduit entry devices or blanking devices
shall not compromise the degree of ingress
protection level IP6X for use in the presence of
combustible dusts.
The unit has an ingress protection of IP66/67
and therefore any conduit device fitted must
maintain this.
