nection. Standardized parts, together with extensive use of quick-connect and plug-in design, minimize downtime and reduce spare parts inventory.
No stand-by supervision needed when you install an ElectriK Tel-O-Set Control System. Installation crews never have to open an instrument cover to hook up the line . . . instrument crews never have to touch an outside line to service an instrument. It's all in the Tel-O-Set connection system. All process connections are entirely isolated from the inside of the instrument case. Installation crews can mount, pipe, and wire the various Tel-O-Set instruments without removing the cover. Instrument chassis can be removed for servicing without breaking any external process or electrical con
And there's more to the ElectriK Tel-O-Set economy story. Specifically, there's no external power required at any field-mounted Tel-O-Set instrument. Line power con nection is made only at the receiver. Two-wire d-c trans mission reduces installation costs and eliminates shielding problems. Also, the 4-20 milliamp signal range of the system gives a live zero and permits the use of the most reliable transistors available. The d-c signal can be fed into data handling systems and millivolt-actuated instruments . . . can be easily transduced to a standard 3-15 psi pneumatic signal to operate existing pneumatic systems.
