Frequently Asked Questions

What is the output signal of the PT-511 transmitter and how do I wire it?

The PT-511 provides a standard 4-20mA two-wire current loop output. In a typical installation, you connect the positive supply wire (typically 12-24V DC) to the transmitter's positive terminal, and the transmitter's negative terminal connects to your PLC or receiver's analog input. The same two wires carry both power and the signal, simplifying wiring.

What is the meaning of the 0.5-1% accuracy rating?

This rating indicates the transmitter's maximum error as a percentage of its full-scale range (6 MPa). A 1% accuracy means the reading could be off by up to 0.06 MPa (6 MPa * 0.01). The actual error within the specified operating temperature range will be between 0.5% and 1% of full scale, depending on calibration and environmental conditions.

Is this transmitter suitable for systems with water hammer or pressure spikes?

Yes, the PT-511 is specifically engineered with resistance to water hammer impact. Its internal sensing and damping mechanisms are designed to handle the rapid pressure surges common in pumping and fluid control systems, protecting the sensor core and ensuring long-term reliability and stable readings.

Can the PT-511 operate in cold or outdoor environments?

Yes, with an operating temperature range of -40°C to +85°C, the PT-511 is well-suited for harsh outdoor environments, unheated industrial spaces, and applications subject to wide temperature swings. Its components and housing are selected to maintain performance across this broad range.
