Description

The OULD PT-506 Water Pressure Transmitter employs a high-stability piezoresistive sensing element paired with an advanced signal conditioning ASIC. This integration provides precise conversion of mechanical pressure into a standardized 4-20mA analog signal, ensuring high immunity to electrical noise and voltage drop over extended cable runs. The transmitter’s internal MCU and EEPROM allow for programmable calibration and configuration, supporting field adjustments.

Engineered for demanding water and HVAC applications, the PT-506 features a robust housing and sealing design that protects against water ingress and mitigates the damaging effects of pressure spikes and water hammer. Its wide operating temperature range from -40°C to 85°C ensures reliable performance in both outdoor and industrial environments, delivering long-term stability and a high performance-to-cost ratio.

Frequently Asked Questions

What is the wiring configuration for the 4-20mA output?

The PT-506 uses a standard two-wire 4-20mA loop. Connect the positive supply (24VDC+) to the transmitter's power terminal, and the output current signal is drawn from the same wire. The return line completes the circuit to your PLC or receiver's analog input, which typically includes a precision resistor (e.g., 250 Ohm) to convert the current to a voltage signal.

Can this sensor be used with aggressive fluids other than water?

The PT-506 is specifically designed and sealed for water applications. Its wetted materials are selected for compatibility with clean water. For aggressive chemicals, oils, or other media, a sensor with a compatible diaphragm material (e.g., Hastelloy, Tantalum) and fluid compatibility certification is required. Consult the manufacturer's datasheet for specific material details.

How is the sensor calibrated, and can it be done in the field?

The transmitter features a built-in MCU and EEPROM, allowing for programmable calibration. Field calibration typically requires applying known pressure points (e.g., zero and full scale) and using a compatible handheld communicator or calibration tool to send commands via the interface (details are model-specific). The EEPROM can be reprogrammed multiple times.

What does 'water hammer resistant' mean for installation?

Water hammer resistance means the sensor's internal sensing element and housing are designed to withstand sudden, high-pressure spikes caused by rapid valve closure or pump starts/stops in piping systems. While resistant, for optimal longevity, it is still recommended to install pressure snubbers or pulsation dampeners in systems prone to severe water hammer.
