The Jerguson Model JMS-100 series Liquid Level
Switch is a compact integral ultrasonic gap switch with all 316-SST
Or Teflon Wetted parts.
It uses proven ultrasonic technology to operate in virtually
any liquid regardless of viscosity. The JMS-100 utilizes a gap
sensor with internal piezoelectric crystals to transmit and receive
an ultrasonic signal. When liquid is present the ultrasonic signal
is transmitted across the "gap" and sensed by the receiving
crystal which in turn generates an electrical signal. The electronic
module detects this change and produces a change in the DPDT
output relay state or 4 mA dry, 20 mA wet output.
The JMS-100 consist of a 316-SST or Teflon sensor and an integral
miniturized, encapsulated electronics which is mounted in
a cast aluminum, Explosion Proof, NEMA 4X enclosure. |
