Our rf level switch is widely applied in various products such as building industry materials, cement, sand, lime, milk powder, flour, salt, food grains, powder, granular, chemical and mining etc. These comprise of a specially designed electronics and sensing probe using driven shield coat guard circuit and corresponding 3-element probe.
The electro-mechanical combination of the coat guard technique is there makes the system immune to the material build-up on the probe and material bridging between the probe and the hopper wall. The measured signal does not flow to the hopper wall through the probe in the backward direction but flows only through the material.
The salient features of this level measuring instrument are as follow:
three element coat guard technology
can be configured either for high or low level point switching
reduces the inventory cost
ignores material build-up on the probe
suitable for the highly dusty environment
high reliability
fast and easy installation simple calibration
field selectable operation logic
provides economical solutions
various models not required
the specifications of these point level switch are as follow:
switching unit:
housing: aluminum, weather proof, powder coated. Integral with the probe suitable for back panel mounting
cable entry: 2 nos.
Ambient temperature: 0 ° c to +60° c
power consumption: 1.9 va
mains voltage: 230110 v ac (+-15%), 50 hz or 24 v dc
output: 2 sets of potential free co contacts rated at 5 amps, 230 v ac for non-inductive loads
switching delay: continuously adjustable from 1 to 20 sec. Probe free or probe covered (optional)
safety operation: field selected switch over for min. Or max. (fslfsh) switching points
switch status display: green led shows normal, red led shows alarm, yellow
led shows power on condition
