Product Code: DT-55L Product Name: DT-55L hammer level meter Product Category: hammer level meter I. Overview and Application hammer level meter (sensor) is mounted on the top of the silo, detecting sensor Process control signals from the display and control instruments. Sensors detect received instruction: motor forward drive gear shaft and the winding drum rotation, so that the cable decentralization, driven hammer down from the warehouse roof. When the hammer fell to the material surface is lifted material surface and weightlessness, cable slack, sensitive jog lever action switch contact, display devices reverse the motor control signal is issued to give instructions immediately return the weight to rise until the bobbin hit the top of the switch, the motor stops and the hammer back to its original position warehouse roof, complete a detection process. In this process, display and control instrument calculates the weight to height from the warehouse at the end between the material surface and 4 ~ 20m A output current by detecting the number of revolutions of the bobbin. Suitable for measuring powder, granule and bulk solids materials. Second, product characteristics ● unique structure and transmission mode ● overcome the past, many other forms of hammer level meter recurring problems ● can detect computer remotely ● ● automatic and manual hand operation and reliable detection of ease, little maintenance , wide range of applications Third, the major technical indicators measuring range: 0-8 / 16/32 m (special specifications can be negotiated) Accuracy: ± 1% F · S Repeatability: ± 1% F · S Resolution: ± 3cm probe Speed: 0.15m / s measuring band: stainless steel wire rope weight Weight: 1.5kg (0 ~ 16m); 2kg (0 ~ 32m) motor stall torque: 5N.m Power: 90W Ambient temperature: -10 ℃ ~ + 60 ℃ Flange Standard: JB81-59 outer diameter of the aperture φ18mm φ195mm hole center distance φ160mm (DN80 PN1.0) and outlet: M20 × 1.5 Dimensions: 8 m: length 430 × height 220 × width 350mm 16 M: length 560 × height 220 × width 350mm 32 M: length 730 × height 220 × width 350mm 50 M: length 850 × height 220 × width 350mm + bottom bracket height φ195 × 110 φ195 × 290mm Fourth, the product selection table Enterprise Standard Model measurement range second table in the form of current output alarm antistatic legend DT Enterprise standard 55L hammer level meter 1 0 ~ 8m 2 0 ~ 16m 3 0 ~ 32m 4 special A horizontal B vertical 0 without 1 with 4 ~ 20mA output 4 ~ 20mA output 0 does not bring the lower limit alarm 1 to a lower limit alarm 1 ESD 2 is not anti-static DT 55L 1 A 1 1 2 complete selection
