It features two interconnected pressure ports, and is equipped with a mounting bracket for simple installation on the workstation. The pressure gauge is available in four versions with different operating ranges: Analog, Low Range, 0 – 100 kPa (0 – 15 psig) Order no. 582374 Digital, High Range, 0 – 690 kPa (0 – 100 psig) Order no. 588234 Analog, Medium Range, 0 – 200 kPa (0 – 30 psig) Order no. 588235 Digital, Medium Range, 0 – 200 kPa (0 – 30 psig) Order no. 588236 2 Float Switch Reed-relay float switch with magnetequipped float. Its mounting is vertical and inside the level column. The reed contact is hermetically sealed and normally closed, with a positioning range of 25 cm (10 in). It operates at atmospheric pressure. Order no. 588242 3 Conditioning Unit (Single Port) Conditions and regulates the pressure of the air supplied to the pneumatic circuits. It consists of a main shutoff valve, filter, a pressure regulator, pressure gauge, sleeve valve, and a muffler. It requires compressed air from a central air supply or a portable unit. Order no. 588111 4 Pumping Unit Consists of a centrifugal variable-speed pump having a flow of 0 – 12 l/min (0 – 3.2 gal US/min) and a maximum pressure of 100 kPa, gauge (14.5 psig). The pump motor has a rated speed of 3600 rpm at 60 Hz and 3000 rpm at 50 Hz, with a power of 0.37 kW (0.5 hp) at 60 Hz and 0.25 kW (0.33 hp) at 50 Hz. The Pumping Unit includes a built-in Powerflex 525 ac drive from Allen-Bradley. This ac motor drive has an output voltage of 0 – 230 V ac, an output frequency of 0 – 240 Hz, and is controlled using either 4 – 20 mA signals or an Ethernet/ IP digital communication with AllenBradley PLC’s. The Pumping Unit also features a convenient communication interface to configure and monitor all the drive’s parameters. The nominal current of the Pumping Unit is 3 A at 120 V 60 Hz and 1.5 A at 220 – 240 V 50 Hz. 120 V, 60 Hz 595991 220 – 240 V, 50/60 Hz 595992 5 Metering Pump Device whose pump motor has an excitation voltage of 0 – 12 V dc and a nominal current of 2 A. The pump has a flow of 0 – 2.52 L/min (0 – 0.67 gal US/min), a maximum pressure of 145 kPa (21 psi), and a maximum temperature of 93 °C (200 °F). Order no. 588212 6 Metering Pump Drive Device with three 0 – 5 V dc or 4 – 20 mA inputs and an output voltage of 0 – 10 V dc. It is controlled using three 0 – 5 V dc or 4 – 20 mA control inputs. It can operate in either continuous mode or pulsed mode.
