PTG series Smart Pressure Transmitter Model PTG71 / PTG72 OVERVIEW The Smart Pressure Transmitter model PTG is a high- performance, highly reliable gauge pressure transmitter. Based on Azbil Corporation's proven Smart Transmitter technologies, the model PTG offers improved performance and reliability with size, weight and cost advantages. An optional, built-in digital indicator allows the pressure transmitter to be used in a wide variety of applications. The model PTG can also enable two-way communications between CommPad (Smart Communicator), or HART 375 communicator, and, via DE protocol, a TDCS3000 or 3000X and a database, thus facilitating self-diagnosis, range resetting, and automatic zero adjustment operations. CE mark Model PTG71G screw type Type of protection • Water and dust proof for IEC IP67 • FM Explosionproof • FM Dust-ignition-proof • FM Intrinsically safe • KOSHA Flameproof • NEPSI Flameproof • NEPSI Dust ignition-proof • ATEX Flameproof FEATURES Compact and lightweight • Approx. 0.9 kg (Screw connection type) Broad range setting • Range from -100 kPa to 50 MPa. • Span from 2.0 kPa to 50 MPa. Note) Screw connection type. Covered with five ranges. China RoHS This device is used in the Oil & Gas, Petrochemical, Chemical, Pulp & Paper, Food & Beverage, Machinery, Steel/Metal & Mining, and Automobile industries and therefore does not fall under the China RoHS Legislation. Remote communication Any range can be set using the Smart communicator or the HART communicator (available separately). This further increases range flexibility and keeps inventory down. If this device is used in semiconductor manufacturing equipment, labeling on the device and documents for the China RoHS may be required. If such documents are required, consult an Azbil Corp. representative. Built-in digital indicator The built-in digital indicator option effectively checks output on site. Specifications are subject to change without notice.

Azbil Corporation Oil and water free finish Oil and water are removed from the wetted parts before shipment. Electrolytic grinding (For ferrule type only) The surface of the wetted parts is smoothed by electrolytic grinding. Passive state finish (For ferrule type only) The surface of the wetted parts is treated with a passive state finish to form a protective film to increase resistance to corrosion. Test report The test report indicates the results of appearance, I/O characteristics, insulation resistance, and breakdown voltage tests. Material certificate The material certificate shows the...

Azbil Corporation Transmitter handling notes Handling precautions for HARTspecification devices To get the most from the performance this transmitter can offer, please use it properly noting the points mentioned below. Before using it, please read the Instruction Manual. • "If you need to operate with a secondary host (HART communicator, etc.), set the communication interval of the primary host (DCS, device management system) to 8 seconds or more, or suspend communication from the primary host. If the primary host repeats HART communication within 8 seconds, the request from the secondary...
