F-Series: F170

Field mount - Level monitor

with high / low alarms and analog outputs

The F170 is a versatile level indicator featuring continuous level monitoring. It offers the ability to set two low and two high level alarm values. If desired, an ignore function can be set up to allow for an incorrect level for a certain period of time. Up to five outputs are available to transmit alarm conditions and actual level.
The display shows the actual level, height or percentage, alarm values, alarm messages and status. On-screen engineering units are easily configured from a comprehensive selection.

Advantages
  • Robust IP66, IP67 (NEMA Type4X) field enclosure. It is so rugged, you can even stand on it!
  • Intrinsically Safe available - ATEX and IECEx approval for gas and dust applications.
  • Programming can be done by your own crew, with the sensible menu-driven structure, saving cost and irritation. Know one, know them all!
  • Very diverse mounting possibilities: walls, pipes, panels or directly onto outdoor sensors.
Application overview F170

Features

  • Level monitoring: four alarm values can be set: low-low, low, high and high-high level alarm.
  • Alarm values can be changed by the operator or they can be password protected.
  • Analog output to transmit the actual level.
  • Level and alarm values: six large 17mm (0.67") digits.
  • Displays level, height or percentage, measuring unit and alarm messages simultaneously.
  • Alarm ignore function allows an incorrect level for a certain period of time.
  • Selectable on-screen engineering units; volumetric or mass.
  • Displays clear alarm messages.
  • LED backlight.
  • Backup of settings in EEPROM memory.
  • Ambient temperature: -40°C to +80°C (-40°F to 176°F).
  • Various accessories are available for this product.
  • The F-Series is so rugged, even a truck can stand on it!

Level Inputs

  • (0)4 – 20mA.
  • 0 – 10V DC.

Alarm Outputs

  • Function: Configurable alarm outputs for low-low, low, high, high-high or all combined level alarms.
  • Type: Up to three passive NPN transistors or active PNP transistors or up to four isolated electro-mechanical relays.

Analog Outputs

  • Function: Re-transmitting the actual level - the output can be scaled to any range (e.g. 2.5 m³ to 1400.0 m³).
  • Type: One passive isolated, floating or loop powered 4 – 20mA output or one active (0)4 – 20mA or 0 – 10V DC output.

Applications

  • The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).
  • Level measurement and continuous level monitoring is desired as well as signal re-transmission of the level or serial communication.
    Alternative basic models: F070, F073, F077. Alternative advanced model: F173 or the D-Series basic DIN panel mount indicators.

Power Supply
