Differential Pressure Switch ILH351
Series of ILH351 differential pressure switch has been designed for interlock purposes or no differential pressure detection. Where critical or high value property is to be maintained within specific environmental conditions, a single control should not be applied to function as both an operating an d safety dev ice . In such application s, a separate back-up control wit h alarm contacts should be wired to indicate when this control operates.

General Information
Series of ILH351 pressure switch can be used to sense (Differential) pressure and flow of air in ducts and pipes.
Typical applications include:
- Filter obstructive alarm.
- Air proving in ventilation ducts.
- Maximum airflow controller for variable air volume systems.
- Burner air controlPressure Connection and Wiring
Pressure connections are marked with, Incorrect connections are forbidden.
Installation
Location: select a location where vibrations are minimal. Ambient temperature should be within the range of -15/ +60℃ .
The production calibration of the ILH351 is made at room temperature;mounting locations close to room temperatures are preferred .In systems with high humidity where condensations possible, thus the entranceshould point downwards.
Mounting Instruction
The switch is preferably mounted with the diaphragm in a vertical plane , unless the device is set or calibrated for horizontal mounting as on special customer models . On these models the mounting position is indicated on the side of the control .It may be fastened directly to the duct, heater or panel as long as the mounting surface has minimal or no vibration.
Pressure connections are marked +(high pressure) and - (low or static pressure). For more informaton, please read the diagram on the side of the control.
Notice
To drill a hole through the plastic tube or pipe before installation, and also mount part of L-bracket on the spot (Standard setting).
Accessory Consists
(φ 6.2mm 1.8m) plastic tubes,
1 L-bracket, 3 screws,
2 pressure-adapted tubes
*The Pressure Switch should be mounted vertically which can prevent affecting on precision from inner atmosphere film weight.
*To prevent electrical shock or damage to equipment , when the cover is removed ,ensure the power supply is switched off .
*Complete wiring and check the connections before applying power . Incorrect wiring may cause permanent damage to the unit .System Check
After proper installation and adjustment of the control, running at least one full cycle of the equipment should check the system. If anything appears to operate incorrectly, the wiring and components should be rechecked
