ILH311 series flow switch is a automatic element of protecting and controlling flow in the tube that are used in liquid lines carrying water, ethylene glycol, or other liquid not classified as hazardous. Liquid temperature,range:5°C~-120°C Max. working pressure:1.0Mpa;
IILH332 series flow switches are used in measuring and controlling the flow of the liquid in the pipe, such as water, alcohol, etc.,as well as in the places where it needs chain effect or cutout protection. ILH332 series flow switches have SPDT switch, full-sealing structure as its shell, and stainless steel as its inside components, which can assure its use in any conditions. ILH332-A series flow switches are used for caustic fluid liquid,the materials of ILH332-A in contact with th medium is stainless steel. Approvals: DnV,Det norske Veritas(Norway),CQC(China),CE (Europe).
The ILH333 Flow Switc has Are Single-Pole, Double-Throw (SPDT) flow switches that are used in liquid lines carrying water ,ethylene glycol, or other liquids not classlfied as hazardous. They can be wired to energize one device and de-energize an-other device powered from the same source when liquid flow either exceeds or drops below the set flow rate. Note: The ILH333 Flow Switch can not be used where the liquid in the pipes will drop below the liquid’s freezing point , causing an internal freeze-up.
ILH341-T series temperature control is a temperature-controlled electric switch, can be directly connected to single-phrase A.C. motors of up to about 1KW, or installed in the control current circuit of D.C. motors and large A.C. motors. ILH341-T series temperature control has a single pole double throw (SPDT) changeover switch. The position of switch depends on temperature control setting and bulb temperature.
ILH342 frost protector controller mainly have the function of anti-freezing, used to guarantee system temperature is not lower than set value.
Differential Pressure Switch ILH350
ILH350 Differential pressure switch is pressure electric switch operation,can be used to measure air and ono-corrosive gas with diaphragm material compatible of the absolute pressure,differential pressure,gauge pressure and vacuum negative pressure. ILH350 Differential pressure switch in the ventilation duct is used as a switch or differential pressure switch to monitor the air filter and fan start-stop state,also applies to the primary and secondary level of wind valve control system. ILH350 Differential pressure switch is also very suitable for prevent heating coil overheating and monitor industrial air cooling circuit.
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.
