PH electrochemical electrode Spraywash

LTH Electronics offer spray wash cleaning adapters for their pH electrode systems to reduce maintenance and improve electrode life in applications where a pH or Redox electrode bulb is prone to coating. They provide an effective method of cleaning the electrodes in both in-line and dip applications. The spray wash fittings have a full coned spray nozzle which is mounted under the pH or Redox electrode bulb with a cleaning solution of 4 litres per minute being applied at a pressure of 4 Bar. The spray wash fittings can be supplied with an isolating break tank with ball valve and a pump supplied in a wall mounting enclosure. The break tank incorporates a simple ball float valve to comply with local by laws and will isolate the spray wash system from the water supply. The electrically operated pump provides a suitable wash supply via a positive displacement 3 chamber diaphragm system. The pump incorporates a check valve to prevent reverse flow and will self prime up to a vertical height of 2.5 metres. A pressure switch will cut off the pump in an over pressure situation and a thermal cut out protects the pump motor. The pump is housed in a wall mounting polycarbonate enclosure with electrical connections for the pump power supply and the liquid connections are made via push-in tube connectors. Tubing should be ordered extra as required. When the spray wash system is used with either the LTH MXD70 Series or HPT63 Advanced pH transmitter it is possible to control the operation of the cleaning cycle. It is possible to configure one of the set point relays as a Clean output. The Clean duration, Recovery time and Interval period are all programmable via the front keypad.
