PRESSURE OR TEMPERATURE INPUT PNEUMATIC CONTROL OUTPUT PROPORTIONAL, INTEGRAL, DERIVATIVE, DIFFERENTIAL GAP & ON/OFF CONTROL DIRECT OR REVERSE ACTION PANEL, SURFACE OR PIPE MOUNTING ELECTRICAL ALARMS (RELAYS) AUTO MANUAL REMOTE PANEL IP-54 ENVIRONMENTAL PROTECTION The 93 Series Pneumatic Indicating Controllers are highly reliable instruments equipped with either a heavy duty temperature sensing system,anaccurate pressure sensing element, or a flow measuring system. They are used to indicate a direct pressure input and to provide a pneumatic output signal for control. The 93 Series can be equipped with single term (P), two-term (P+I) or (P+D), three-term (PID), on/off or differential gap control actions to provide pneumatic control output(s). To enable accurate matching to plant conditions, the proportional band, integral time and derivative time are adjustable over a wide range. For applications that the control output must be switched to its maximum at a certain point, and be switched to its minimum at another point, choose the differential gap control action. The switching gaps are equally spaced and adjustable between 1% and 100% of the range. TInternal or external Auto/Manual (AM) control can be ordered as an option. he output value is indicated by a pressure gauge visible on the face of the instrument. The controller is housed in a strong moulded case that can be panel, surface or pipe mounted. Agasketed door protects internal components from harsh industrial environments and offers IP-54 protection.
