Assembly-type duct sensor EKF with passive output

Technical data

Application

Housing colour: Housing material:

pure white, like RAL 9010

The assembly-type duct sensor EKF is used for measuring tem- peratures in liquids and gases in pipes, air ducts or tanks. A mounting flange (MF) is required for use in air ducts. If used in liquids, immersion sleeves made of brass with nickel plating (THMs) should be used. For aggressive media, immersion sleeves made of stainless steel V4A (THV) are recommended. Immersion sleeves or mounting flanges are not part of the delivery scope and must be ordered separately as accessories. Accessories: mounting flange for installation in air ducts: MF matching immersion sleeves in brass: Im- mersion sleeves with brass plating can be found in the ‘Miscellaneous’ section matching immersion sleeves stainless steel (V4A): immersion sleeves made of stainless steel can be found in the “Miscellaneous” section Sensor wire extendable: depending on the cross-section of the conductor and the sensor unit type

PA plastic (30% GF reinforced)

Sensor tube material: Ambient temperature: Max. sensor temperature Permissible atmospheric humidity: Electrical connection:

V2A (1.4301) −30 … +70 °C

150 °C

max. 95% rel. humidity, non-con- densing screw-type terminals 0.14 mm² up to 2.5 mm² only to safety extra low voltage max. 30 VAC/42 VDC

Tolerances:

PT100 / PT1000

DIN EN 60751 B

Mounting/attachment:

in immersion sleeves (THMs, THV) for fluids or with mounting flange (MF) in air ducts

Protection rating: Protection class: Safety and EMC:

IP 65

according to DIN EN 60730

Sensor characteristic curves:

the sensor characteristic curves can be found in the “Miscellaneous” section From the fitting length (EL), subtract 15 mm to determine the nominal length (NL) of the immersion sleeve, for example, EL = 65 mm corre- sponds to THV/50

Immersion sleeves:

Please follow the EMC directives, avoid parallel routing with mains voltage-bearing wires, or use shielded wires.
