UFI Pressure Filter Indicators

The UFI Pressure Filter Indicators are essential devices for monitoring clogging in medium- and high-pressure hydraulic filters. The range includes analog pressure gauges with a 0–12 bar scale, SPDT pressure switches set at 1.5 bar, and a wide selection of visual and electrical differential indicators with set points from 1.3 to 8 bar. Also available in versions with thermostat, LED signaling, and ATEX certification, they ensure reliability and operational safety.

UFI Pressure Filter Indicators

Description

Clogging Indicators for UFI Pressure Filters: Advanced Control and Safety

UFI clogging indicators provide precise and reliable solutions for monitoring the condition of filter elements in pressure lines. These devices detect the pressure differential caused by contaminant buildup, promptly signaling the need for maintenance to prevent system malfunctions.

Types and Functions

The range includes various configurations to meet every application requirement:

  • Pressure Gauges (Series 31-33-36): Instruments with a 0 ÷ 1.2 MPa (0 ÷ 12 bar) scale, ideal for direct pressure reading. Also available in stainless steel with glycerin filling for heavy-duty applications.
  • Pressure Switches (Series P1): SPDT switches with fixed setting at 150 kPa (1.5 bar), compatible with FMA, FPE, and FPH filters.
  • Visual Differential Indicators (Series 5B-5D-5E-5F): Immediate local indication with available settings at 1.3 bar, 2.5 bar, 5 bar, and 8 bar.
  • Electrical Differential Indicators (Series 6B-6D-6E-6F): Provide a remote signal when the set pressure is reached (from 1.3 to 8 bar).
  • LED Indicators (Series 7B-7D-7E-7F): Integrate visual LED signaling with the electrical signal.

Special and Technological Versions

For complex applications, UFI offers indicators with advanced features:

  • With Thermostat (Series T0-T2-T3-T6): Electrical differential indicators with signal lockout below 30°C, preventing false alarms due to cold oil viscosity.
  • Electronic (008.0265.2 – 008.0266.2): Differential pressure sensors with 4–20 mA analog output and PNP digital outputs, ideal for continuous and precise monitoring.
  • ATEX: Electrical differential indicators certified ATEX 3 GD EEx and T6 for use in potentially explosive atmospheres.
  • Vandal Proof (Series M2-M3-M6): Robust electrical differential indicators with IP65 protection.

Technical Features

The indicators are manufactured with a brass body and NBR or FKM seals. Electrical versions provide IP65 protection (DIN 43650 connector) or IP67 (M12 connector), ensuring operation even in harsh environments.
