1 MAKING MODERN LIVING POSSIBLE Technical brochure Liquid Level Sens /4100U /4100U - Cable Version /4100U - Coaxial Version The /4100U liquid level sens is designed specifically measure liquid levels in a wide range of refrigeration applications. The /4100U liquid level sens is based on a proven techhology called Time Domain Reflecmetry (TDR) Guided Micro Wave. /4100U liquid level sens can be used measure the liquid level of many different refrigerants in vessels, accumulars, receivers, standpipes, etc. The electrical output is a 2-wired, loop powered 4-20 ma output signal, which is proptional the refrigerant liquid level. /4100U in a cable version is suitable f most commonly used refrigerants, including R717(ammonia), HCFC, HFC and non crosive gases/ liquids except CO 2, and differing lengths from 800 mm(31.5 in.) and up (197 in.). The coaxial version of /4100U is designed f use with CO 2. It can also be used f all other appoved commonly used refrigerants. The /4100U coaxial version should always be used f marine applications f all refrigerant types. The /4100U cable version should T be used f CO 2 marine applications. Dust, foam, vapour, agitated surfaces, boiling surfaces, changes in density in the dielectric constant, εr, f the liquid have no influence on the /4100U perfmance. Oil accumulated in the botm of a standpipe will not disturb the liquid level signal and it is not necessary remove /4100U f cleaning after oil has been drained out of the standpipe. Features Approved and qualified by Danfoss f refrigeration applications One product covering several probe lengths (cable version) A single product f all commonly used refrigerants (cable version) Cable version requires less p-end clearance f installation and service Proven operation with all refrigerants in combination with oil. No need clean cable version when fully covered by oil. The cable version is very compact and easy handle, ship, install and use with different lengths and refrigerants Changes of the liquid dielectric constant (εr) do not affect operation. (197 in.) probe length with cable version 2-wire loop powered; no separate transfmer needed. Please Note: If used gether with Danfoss EKC 347 Level Controller, a V d.c supply is required. Multi language HMI. Level and setting readout in mm,cm,m( ft, in.) F further details regarding mechanical and electrical installation please refer the product instructions PI.SC0.D (CABLE version) and PI.SC0.E (COAXIAL version).

5 Liquid Level Sens, /4100U Measuring principle (Cable and Coaxial) 1. The electromagnetic (EM) pulse is transmitted by the signal converter 2. The pulse goes down the probe at the speed of light in air, V1 3. The pulse is reflected 4. The pulse goes up the probe at speed, V1 5. The converter receives the pulse and recds the signal 6. The EM pulse moves at speed, V1 7. Transmitted EM pulse 8. Half of this time is equivalent the distance from the reference point of the device (the flange facing) the surface of the product 9. Received EM pulse Main technical data (see a complete list of all technical data on page 11) The /4100U electronic converter emits low-intensity, high frequency electromagnetic pulses with a width of approximately 1 nanosecond, which travel at the speed of light along the probe (wire coaxial cable) down the liquid surface. The pulses are reflected by the liquid surface, guided back along the probe, and received and analysed by the /4100U electronic converter and then converted in a liquid level reading. This method is called time domain reflecmetry (TDR) guided microwave. The dielectric constant, εr, of the liquid is a key parameter and has a direct impact on the degree of reflection of the high frequency electromagnetic pulses. Liquids with high εr values, such as ammonia, produce strong reflections, while liquids with low εr values, such as CO 2, produce weak reflections. Supply Voltage V d.c. Min/Max.

If the temperature condition in the standpipe/ vessel is known, a constant (dielectric constant of the refrigerant gas) can be entered (parameter GAS EPS.R), in der obtain improved Top and Botm Dead Zone values.
