Electronic Level Instrumentation
We are your single source for a complete line of electronic level instrumentation to meet any process application.
 Ultrasonic Point Level Switches
Penberthy level switches employ ultrasonic gap sensing technology to provide level indication in nearly any liquid. To meet a wide
range of requirements, LEVELMARK™ gives you a choice of single or dual-point models, with 4-20 mA loop, optoisolator (optoisolated
open collector transistor) or relay output options. What’s more, these gap switches are available FM-approved/CSA-certified
explosion-proof and/or intrinsically safe.
Ultrasonic Continuous Level Transmitters
Choose from a variety of systems designed to deliver dependable performance in difficult, “non-contact” environments. Penberthy
transmitters feature easy calibration with a number of available configurations, including digital displays, alarm relays, standard
temperature compensation, 0 to 30 second delay and echo loss/fault indication.
NEW WAVE CAPACITANCE™ Level Transmitters & Switches
Penberthy’s LEVELMARK™ New Wave Capacitance technology, including explosion-proof switches, transmitters and XP and IS
probes, provides unprecedented levels of accuracy and safety in capacitance-based level measurement systems. Offering highly accurate,
time based reference measurement similar to digital multimeters, these instruments deliver accuracy of ±0.25% of reading, high
level of immunity to RFI and EMI interference and “no-drift” calibration. LEVELMARK™ switches and transmitters also
come standard with a two year warranty on instruments, probes and approved applications.
