SM39-DH01P HART protocol intelligent pressure transmitter
The SM39-DH01P HART protocol intelligent pressure transmitter is a high-precision, high-stability, multi-parameter, 4.5-digit LCD display intelligent pressure measurement product that complies with the HART protocol. Users can use a HART communicator to manage, adjust, or monitor process variables of HART instruments in operation, or use buttons for on-site configuration, which is convenient to operate. With precise digital temperature compensation and non-linear correction technology, a safe and reliable explosion-proof structure design and standardized signal output, it features high accuracy and a wide measurement range, suitable for places requiring precise measurement of fluid pressure. This product operates in a two-wire mode and can directly replace analog two-wire 4～20mADC output transmitters. It can be widely used in various fields such as petroleum, chemical industry, steel, power, building materials, textiles, pharmaceuticals, food, gas, scientific experiments, and military industry. It has been widely promoted and applied in various oil fields such as Daqing, North China, and Xinjiang, and has won user recognition for its high precision, high reliability, simple installation, convenient maintenance, environmental protection, and durability.

4. External Structure
See Figure 1. External Structure Diagram of SM39-DH01P HART Protocol Intelligent Pressure Transmitter (Unit: mm)
5. Electrical Wiring
Open the instrument back cover (wiring terminal panel) to see the wiring terminals. For power connection, see Figure 2: The left end 1+ (red) and 2- (black) are for sensor power supply and signal wiring, and terminal 3 is reserved. On the right side, there is a rotary switch for controlling battery power supply, and terminal 4 at the top is used to fix the signal line shielding wire.
6. Instructions for Use
6.1. All sensors have undergone digital calibration, and different sensors have complete consistency and interchangeability.
6.2. During transportation, the batteries of all sensors are in the off state. When installing the pressure sensor on site, open the back cover, turn the rotary switch to the "ON" position, and the LCD will display normally, indicating that the battery has been successfully connected. Connect the sensor power supply and signal wires to the left end 1+ (red) and 2- (black) of the 3-pin terminal, install and tighten the back cover. Be sure to tighten the protective sleeve to prevent water leakage.
6.3. To install a pressure sensor on a pipe, first close the needle valve at the sensor installation location; then wrap the sensor threaded connector with Teflon tape; screw the sensor into the pipe connector; open the needle valve and check for leaks. Installation is complete once no leaks are detected.
