Mechanical Pressure Switch for Industrial Pressure Monitoring
The TIVAL FF 444 Mechanical Pressure Switch provides adjustable pressure switching for industrial pressure monitoring and control applications, with different pressure ranges, IP65 protection and UL/CSA approval.
The FF 444 Series is designed for applications requiring mechanical pressure switching at defined pressure levels. The product range includes three order references with different adjustable upper and lower switching points, allowing users to evaluate a suitable version according to their operating pressure requirements. The series covers switching pressure ranges from 3 to 870 psi across its available models.
Adjustable Pressure Switching
The FF 444 range provides separate adjustable upper and lower switching points, with the available settings depending on the selected model. Each version has specified operating pressure limits, test pressure values and standard switching settings.
When selecting a pressure switch, users should consider the required switching range, pressure differential and maximum operating pressure. The model-specific specifications below provide a reference for comparing the three available versions.
Construction and Connection Details
The FF 444 Mechanical Pressure Switch is specified with IP65 protection and UL/CSA approval. The original product information identifies an F (1/4"-18 NPTF) pressure connection, with AlSi12 or stainless steel listed as material options. A 1/2"-14 NPTF cable gland is fitted as standard.
The product information also references VDE 0170, VDE 0171, VDE 0660, IEC 337-1 and IEC 553-1.
