Level Transmitter | 220 Loop Powered Level Monitor

12 Recent Views In Stock

The 220 is a higly accurate, intrinsically safe level monitor that has been desgined to operate with digital output flowmeters. With an IP67 weatherproof housing, new tactile keyborad and various mounting options the 220 level monitor is perfect for the most arduous of installations.

The solid state relay outputs provide up to four level alarms and a 25 point non-linearity correction table that allows the instrument to be programmed to fit most tanks. This Level Monitor is powered entirely from the 4-20mA current loop requiring no external power or batteries.

This versatile instrument is fully programmable with setup parameters such as span, offset, alarm levels, etc, stored in a non-volatile memory which will retain all data for more than 10 years without power.

A wall mounting bracket is supplied as standard, while a 2″ pipe mounting bracket is available as an option. Alternatively, the Model 220 can be supplied as a panel mount instrument. The Model 220 is housed in an attractive IP67 (Nema 4X) polycarbonate enclosure which is completely watertight. 

220 Level Monitor features

• Non-linear Tank Correction
• Density Correction
• Four Level Alrams
• Level Bar Graph Display
• Tank Contents Display
• Powered by 4-20mA Loop
• Intrinsically Safe
• Wall, Pipe and Panel Mounting
• Watertight to IP67 (Nema 4X)
• ATEX, IECEx, CSA Approved
• CE Compliant

Display

Level bar graph

Displays measured level as a percentage (0 - 100%)

 

Contents

7 digit numeric display of contents with programmable span. An offset can be programmed to account for conetnts remianing in the tank whne the measured level is 0%. The contents are displayed with 42 digit resolution so that larger values are displayed iwth trailing zeros (for example: 1437765 would be displayed as 1437700 and 5467289 would be displayed as 5467000)

 

Filter

A programmable filter will filter out fluctuations in readings caused by agitation in the tank.

 

Density

Density correction is provided for level devices which are density sensitive. Should the desity change, a correction factor can be prgrammed via the front panel.

 

Relays

 

Type 

Four solid state opto-isolated DC relays arranged as high-high, hgh, low and low-low

 

Acknowledgement

Alarms can be programmed for continuous operation or for an acknowledge mode of operation where the display key is pressed to acknowledge and cancel the relay alarm output.

Normally energised or de-energised relay

Relays are programmable to alarm in either mode.

 

Non-Linearity Correction

A 25 point non-linear correction table can be programmed to handle any shaped tank. Up to 25 points on both the x and y axes can be programmed and the Model 220 will perform linear interpolation between points. The curve enables the contents of vessels, such as cylindrical tanks, bullet shaped tanks or hoppers to be displayed directly in engineering units as a volume or mass. A conversion program which runs under Windows 95 is available to calculate theoretical values for the conversion program based on tank dimensions.

Intrinsic Safety

The 220 is certified as intrinsically safe to European ATEX / IECEx standards and CSA US/C standards for both the USA and Canada (refer to specification details for more information)
