P3436

pH Transmitter with 4-20mA output and Modbus

pH Transmitter P3436

The P3436 pH Transmitter and Modbus is an ideal solution for converting the pH Transmitters output into an industry standard 4-20mA output signal, Thanks to a “current loop” 4-20 mA isolated output and RS485 serial interface, the pH transmitter can be easily connected to the most common PLC or other remote supervision and control systems.

The P3436 pH Transmitter is enclosed in a wall mountable waterproof enclosure to allow for close mounting to a pH Electrode system


pH Transmitter Introduction

The P3436 pH transmitter is the best solution for the installations where it is necessary the retransmission of the measures at distance. Thanks to a “current loop” 4-20 mA isolated output and RS485 serial interface, the transmitter can be easily connected with ease to the most common PLC or other remote supervision and control systems.

The P3436 pH Transmitter allows easy installation due to its small size and removable terminal blocks to facilitate the installation and maintenance in control cabinets or waterproof enclosures for DIN Rail Components.

4-20mA pH Transmitter offers easy Calibration

The calibration and the configuration of the P3436 transmitter can be done locally or remotely via the serial interface with the use of dedicated keys, standard solutions such as pH 4, pH 7, pH 9 and 220mV are already stored within the transmitters memory and are automatically recognised when calibrating the device.

The P3436 pH Transmitter contains filter software and can set two filters to obtain a stable reading and faster response to the variations of the measurement in the process, The P3436 supports both Analog & Digital modes that can be used simultaniously.
