Voltage/Load Capacity Ratings |
N/A The KING-GAGE® D/P Transmitter requires a source of DC power for operation. The minimum excitation voltage necessary for the transmitter is 10 Vdc. Any receiving components (meters, data recorders, programmable controllers, etc.) installed in the process loop circuit must be taken into account when determining the required power supply voltage. The internal resistance of each device added together represents the total "load" residing on the circuit loop. |

Differential Pressure Purge Control |
N/A
Unit incorporates differential air flow regulator with flow control orifice Fixed differential set to nominal 10 psid Output is 1:1 pneumatic pressure (hydrostatic force equivalent) Includes an integral differential pressure (D/P) transmitter converting pneumatic pressure into 4 mAdc to 20 mAdc electronic output |
Pressure to Milliampere (mA) Conversion |
N/A
KING-GAGE® D/P Transmitters accept either gage or differential pressure pneumatic inputs that are converted to a proportional 4-20 mA output signal. This two wire signal loop is compatible with typical process components that accept analog input including PLCs. Designed to operate over a broad voltage range, these transmitters work with power sources ranging from 14-40 Vdc (based on load requirements). Output current limiting and continuous no-load operation ensures reliability in even the most demanding situations. Isolated test meter terminals permit in-process monitoring for troubleshooting. This allows the user to easily check the transmitter output without having to remove it from the process loop circuit. |
Pressure Ranges are Span Adjustable |
N/A Transmitter span accommodates a 3:1 turndown ratio (3:1 turndown ratio is applicable to 0-10 and 0-30 nominal range, refer to specifications for detailed span adjustment available on specific range models.) to match the application pressure range (i.e., tank depth). This permits ranging of the device to provide full scale output for maximum resolution in process control operations. Individual transmitter ranges of 0–5 through 0–50 psid are offered. These yield far greater stability than comparable single range units requiring high turndown ratios to fit the application. |
Differential Pressure Pneumatic Sensor Controls |
N/A
The KING-GAGE® D/P Transmitter is also offered in a hybrid version combined with an air flow control for pneumatic sensors or downpipe (bubbler) systems. These combination units allow for direct 4-20 mA signal from the tank using the integrated differential pressure transmitter D/P Sensor Controls are designed for use with KING-GAGE® pneumatic diaphragm sensors. The air control portion of these units creates a 1:1 pneumatic pressure directly proportional to liquid depth in the tank. Acting as a force balance, the pneumatic pressure offsets the hydrostatic pressure exerted against a diaphragm at the tank. The electronic transmitter then converts this pressure into a 4-20 mA output signal. D/P LiquiSeal™ Controls and D/P Purge Controls are used in conjunction with a downpipe (or bubble tube) extending down through the liquid contents of the tank. This type of sensor also acts as a force balance. A continuous purge of compressed air into the pipe displaces the liquid and creates a pneumatic pressure equivalent to hydrostatic head pressure. The transmitter converts this pressure into a 4-20 mA output signal. |

Tank Gauging Applications |
N/A
Acting on the force balance principle, a pneumatic sensor generates air pressure equivalent to the hydrostatic force created by liquid depth. This pneumatic pressure is directed into the D/P transmitter. Pressure is converted to an electronic 4-20 mAdc output proportional to liquid depth. Twisted pair cabling is used to form the signal loop through which the remote indicator receives the transmitter output The KING-GAGE® indicators shown in these system views correlate the transmitter output to total volume or weight of tank contents. This is determined by using a pressure versus capacity listing corresponding to the actual tank dimensions. |
Transmitter Signal Loop |
N/A
As is typical of two wire transmitters, electrical power to the signal loop is supplied through twisted pair cable. Excitation voltage (+V) is provided by the receiving device or from a separate Vdc power supply installed in the loop. The actual voltage necessary for operation of the system will depend upon the overall load resistance of the loop. In most applications, the KING-GAGE® Digital Indicator or LevelBAR indicator provides 24 Vdc excitation to power the transmitter signal loop. |
