HT5 series metal tube flowmeter
M4 type indicator can install up to two limit switches constitute M4K1 and M4K2 type
indicator. Limit switch is a fork sensor, activated by the metal blade by induction
semicircular pointer on. The switching point by the limit pointer to set the dial at the
switch position display on the dial. Limit alarm switch mounted in the indicator part is
called TG22. TG22 limit alarm switch consists SJ3,5 type initiator, aluminum, etc., by
changing the position of the pointer can be arbitrarily set limit alarm value.
TG22 limit alarm switch with an external transistor relays used in conjunction with
the implementation, lower limit alarm output signal, the transistor relay WE77 / EX-1 and
WE77 / EX-2 includes a power pack, rectifier transistor amplifier and relay output. WE77
/ EX-1 with a set of safety control circuit can be equipped with a limit switch, WE77 /
EX-2 with two safety control circuit can be equipped with two limit switches. Relay normally
open contact work, it is easy to transform jumpers according to the table to change the
way work is normally closed, or normally closed to work with open-circuit fault LED monitor
