Differential Pressure Transmitter PLX DPT 50

Product Overview

Differential pressure transmitters from the PLX DPT 50 series are designed for building automation in the HVAC/R sector. The most cutting-edge transmitters available today measure static and differential pressure and have a single device with field-selectable units, range, and output. multiple measurement units, jumper-controlled field selection, including: psi, inchWC, mmWC, mbar, kPa, and mbar. 8 measurement ranges that can be chosen in the
field, either unidirectionally or bidirectionally (see Model Summary)  Options for proportional output include voltage (0–10 V and 2–10 V). as well as current (4-20 mA). A reasonably priced differential pressure transmitter performance ratio for air cooling applications ventilation engineering. Excellently suited for the differential is the Polwax PLX DPT 50. pressure-based air filter, fan, and air quality monitoring flow, for a comfortable Universal Design  provides environment and maximum energy effectiveness.

This device features 4 -48 channel universal inputs and   allowing simultaneous or individual displayand logging of all 48 channels. It supports data logging to via USB interface, and can be powered by a 230 VDC, USB, or mains adapter. The touch screen with backlight and built-in stand enhance usability. It comes with free software and supports Modbus protocol for compatibility with third-party software. Additionally, it includes a 8-channel scrolling temperature chart and alarm indication for each channel.

It’s clear to you that you require a data logger. In reality, multiple data loggers might be required for your in-circuit electronic testing, temperature validation, or mapping. The cost of four, eight, twelve, or sixteen data loggers is prohibitive. For you, Polwax offers the perfect answer. our line of multichannel loggers, PLX 5000M.

Data loggers of the PLX 5000M series allow for the simultaneous collection of 4, 8, 12, or 16 channels of readings. These loggers can also be linked to the robust P-View Data Logging software from Polwax, allowing for real-time mapping, validation, and in-circuit testing monitoring. Consider a time when you could check whether everything is operating as it should without needing to wait for a cycle or event to finish. In the event that an issue arises, testing can be halted, resolved, and then resumed. Just think of the savings in man-hours.

You may record and monitor temperature on up to 16 channels with the PLX 5000 M and PLX P-LOG. The polwax dataloggers employ PT100 RTD probes with two or three wires. RTDs will typically provide you with improved stability and accuracy. It is possible to use J, K, T, E, R, S, B, and N type thermocouples with the polwax dataloggers. Thermocouples offer several benefits, including greater temperature range application, quicker response times, increased availability, and lower overall cost.
