Pointek CLS sensors provide accurate and reliable level detection even in extremely harsh application environments. They are mainly used in the following industries: chemical, water and water treatment, petrochemical, grinding, grain processing, concrete, food processing, cement, and power generation. Different models are suitable for different occasions, including the compact Pointek CLS 100, suitable for narrow spaces; the Pointek CLS 200 high and low level alarm for various applications; and the Pointek CLS 300 for high temperature, high pressure or vacuum, corrosive chemicals or rough particulate materials.

This document is an instruction manual for on-site instrument installation and product manuals, which introduces the installation brackets, measurement devices, etc.

The RWD32/RWD82 universal controller is an independent electronic universal controller with P and PI response, which can be used for comfort control in HVAC and refrigeration systems. The working voltage is AC 24 V or 220 V, and the application can be selected by the application number. Two universal input points are used for Ni 1000, Pt 1000 resistance temperature sensors and 0...10 V signals. Units can be set to °C, °F, % or unspecified units. One three-digit output or two digital outputs, direct action and reverse action. A digital input for day/night conversion. All data can be entered or changed via the keys on the controller without additional tools.

RDF10 room temperature controller has a liquid crystal display, output switch signal to valve actuator, output switch signal to single-phase compressor, output switch signal to three-speed fan, can be automatic cold/hot conversion, manual cold/hot conversion, normal, energy saving and standby working mode, has anti-humidity damage function, optional installation and control parameters, display room temperature and optional temperature value, minimum and maximum temperature setting value and other features.

The QFM65 duct sensor measures relative humidity and temperature in ventilation and air-conditioning systems. It can be used as control sensor in supply or return air ducts, reference sensor, limit sensor, measurement value display or interface with a building management system.

The document introduces Symaro™ duct-type sensor QFM21, which is used to measure relative humidity and temperature. Its features include operating voltage of AC 24 V or DC 13.5-35 V, signal output of DC 0.10 V/4-20 mA for relative humidity and DC 0.10 V/4-20 mA or T1 or LG-Ni 1000 for temperature. The sensor can be used for controlling supply and exhaust air, reference sensors, limit sensors, etc.
