INTRODUCTION Bumpless Internal Auto Manual Switch

The 93 Series Pneumatic Indicating Controllers are highly reliable instruments equipped with either a heavy-duty temperature sensing system, an accurate 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
This bumpless type switch with high sensitivity ball transfer indicator balances manual pressure from the internal reducer with automatic pressure from the controller.

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

Electrical Control (Alarm Contacts)

The Series 93 controllers may be specified with two electrical alarms, adjustable from o to 100% of scale. The electrical contacts are SPST magnetic type. The relays are insulated for up to 2000 V with a maximum load of 10VA. 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. T Internal or external Auto/Manual (AM) control can be

Pneumatic Set Unit

For remote set or cascade operation, it is adjustable over full scale with high and low limit stops. It will not be supplied, if integral desaturation or electric contacts are specified.

Pneumatic Set Unit with Local/RemoteTransfer Switch

This unit is the same as above, but has switch and reducer for control of local or remote set points. It is not available when the electric contacts or the integral desaturation are specified. protection. A sturdy acrylic window allows the 6" scale, indicating the input value, and the pressure gauge, indicating the values of output signals, to be viewed with the transmitter's door closed.

Integral Desaturation (Anti Wind up)

This is used in batch process control with ±0.5% of scale range set point desaturation accuracy. Setting limits are adjustable between 0.7 and 1.4 bar (10 to 20 psi) and air consumption is 62 l/h. 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. A gasketed door protects internal components from harsh industrial environments and offers IP-54
