The Dynisco PT46xDN is a full-featured, smart digital melt pressure transmitter, combining the reliability of this industry-standard Dynisco pressure transducer with the added flexibility of DeviceNet digital communications. The pressure sensing technology is the same as other Dynisco products, proven in such rugged applications such as Polymer Melt Processing applications. The rugged construction is ideal for harsh industrial environments.

The PT46xDN is easily integrated into any digital control system with a DeviceNet scanner. Continuous pressure data is available in real-time at a minimum digital resolution of 0.01% of full scale (14 bits). Monitoring and configuration of the PT46xDN is accomplished via the DeviceNet network using commerciallyavailable DeviceNet programming software.

The PT46xDN effectively combines the features of a melt pressure transducer, power regulator, alarm monitor, and DeviceNet digital signal conditioner into a single, cost-effective package. Wiring the PT46xDN transmitter is simple and fast by virtue of a standard DeviceNet 5 pin Micro-connector. The PT46xDN is powered directly by the DeviceNet bus eliminating the need for a separate power supply. Multiple DeviceNet Pressure Transmitters can be added to a network using a single DeviceNet Master scanner, making this

approach very attractive when an application calls for multiple pressure transmitters.

The mechanical system (filled assembly) consists of a lower diaphragm, a filled capillary tube, and an upper diaphragm with a strain gage. The filled assembly transmits pressure from the process to the strain gage diaphragm where it is converted to a digital signal. The filled assembly isolates the electronics from

5

GENERAL

the high process temperatures.

The lower diaphragm is the surface in contact with the media being measured. This diaphragm can be made from a choice of materials. The standard material is heat-treated 15-5 stainless steel with DyMaxTM coating. This has average corrosion and excellent abrasion resistance and is similar to 17-4 stainless steel. Other materials are also available such as Hastelloy C-276 which has excellent corrosion resistant properties (but is not good for abrasion). For other materials please consult the factory.

Behind the lower diaphragm is a capillary tube filled to the upper diaphragm. As the process pressure deflects the lower diaphragm, the fill is displaced through the capillary tube to deflect the upper diaphragm.

The upper diaphragm has a strain gage element in the configuration of a Wheatstone Bridge. The deflection of the upper diaphragm causes a change in the resistance of the strain gage and hence a change in the balance of the bridge. The amount of imbalance is directly proportional to the applied pressure. This completes the translation of pressure applied to the lower diaphragm into a usable electrical signal.

Functioning Principle of the Dynisco Filled AssemblyFunctioning Principle of the Dynisco Filled Assembly

Functioning Principle of the Dynisco Filled Assembly

The low level output signal from the bridge is amplified via an instrumentation amp circuit. The amplified signal then goes to the input of the analog-to-digital (A/D) converter.

The PT4xxDN utilizes the DeviceNet Predefined Master Slave Connection Set operating as a Group 2 Only Server. The PT4xxDN supports baud rates of 125K, 250k, and 500k. The node address can be set to any address between 0 and 63. The default baud rate and node address are 125k and 63, respectively. Pressure, alarm, and status data are available via polled I/O messages. Alarm, Warning and Scaling parameters are configured using Explicit messages.

The PT46xDN Transmitter supports Polled I/O Messaging to read “real-time” data. It does not support Cyclic I/O, Change of State (COS), or Bit-Strobe connections. The control system Master must be configured first 8-bit word (Byte 0) of the I/O Message Response as shown in Table 1. Note that the most significant 4 bits of the first byte are reserved for future use. The next 8-bit word (Byte 1) supplies transmitter status information, e.g. reading valid, electronics fault, etc. Further information on alarm and status bits is available in Section 7.4. The remaining 2 8-bit words (Bytes 2 & 3) represent the Pressure Value (PV).

When reading the PV, it is important to understand how the value is scaled by the Engineering Units parameter and the Unity Gain Reference (UGR) parameter.

The PV can be scaled to a variety of engineering units, e.g. counts, psi, bar, etc., by setting the Data Units parameter to the appropriate value as listed in Attribute #02 of Section 7.4.

When reporting the PV in any engineering unit other than counts, a decimal scale factor called the Unity Gain Reference (UGR) is used to convert PV to “real world” pressure. By employing the UGR, the I/O data is presented in a more efficient integer format rather than a floating point. The UGR is factory-set and cannot be changed.

To compute the actual pressure, the control system must simply divide the PV by the UGR (

Pressure = PV /

UGR

).

The PT46XDN series of pressure transmitters can be used in media temperatures up to 400°C. If the pressure transmitter is used in other applications, the safety and accident prevention regulations specific to that application must be followed. Maximum ambient temperature for the electronics housing is +85°C (185°F).

Higher temperature can result in damage and malfunction. Do not install the pressure transmitter in places where this temperature is exceeded.
