Chemical Level Sensors

PRODUCT LINE FEATURES

Suitable for use in diesel fuel and chemical level applications in closed or open tanks
Operating Temperature: -40 to +70C
Ingress: IP68, NEMA-4X, NEMA-6P
User-adjustable with SenixVIEW software (included) for setup, testing and cloning sensors

Tough. Construction

In chemical tanks this means resistance to deterioration from chemical exposure. These rugged, compact ultrasonic level sensors measure a wide variety of liquids from diesel fuel in rail locomotives to chemical tanks in the paper and food processing industries (not suited for high temperature CIP operations). Heavy duty electronics are epoxy potted into a polyvinylidene fluoride (PVDF) housing that physically isolates the transducer and electronics from the chemicals and can withstand exposure to both acids and bases. They are used both indoors and out, and in some of the harshest factory environments. They are also used in liquid level applications where chemical resistance is not required.

Smart. Communications

All CHEM sensors include serial Data Communications to connect with SenixVIEW software or other equipment.

Models come with either an RS-232 or RS-485 interface, with the following communications format:

Selectable Modbus (default) or ASCII streaming protocols
Baud rates from 9600 (default) to 115200 bps
This and more, adjustable using SenixVIEW software

We recommend the RS-485 Serial Data Interface unless connecting to an RS-232 device. The benefits of RS-485 over RS-232 include:

Multi-drop Modbus addressing permits networks of up to 32 sensors
Better noise immunity in industrial environments
Allows longer cable lengths at higher baud rates
Bottom line: more capability at the same cost

If you only need a Serial Data interface all models are available without the analog and switch outputs at reduced cost and power consumption, and use a 4-wire dual twisted pair (plus drain) data cable instead of the standard 9-wire cable.

Smart. Interfaces

Multiple Simultaneous Outputs allow these sensors to connect with almost any type of equipment.

Analog voltage (0-10 VDC) typically used with motor drives and similar equipment
Two analog 4-20 mA current loops (sourcing & sinking) for process industry transmitter applications
Two Switches: Each configurable as Sinking (NPN) or Sourcing (PNP)

Ultimate Flexibility

All sensor outputs are SenixVIEW configurable by the user.

Analogs can be calibrated between any two distances, adjustable analog limits, positive or negative slope, and no-target time delay
Switches have both hysteresis and window modes, time delays (on, off & no target)
All analogs and switches all have response settings for power-on initialization, loss of target echo (delay and state)

Connected: by Wire

Any connection you need…

to PLCs, motor drives, displays, PCs – you name it!
Universal: one sensor = many applications

Connected: To LAN or Cloud

Send liquid levels wirelessly and view them on a LAN or in the cloud using our new AirWire LoRa transmitter:

From in-plant or outdoors up to miles away
Low energy, battery powered transmitter
Tank levels or outdoor bodies of water
Receive high & low level alerts
No subscription service charges
For low data rate applications
No conduit or power required

Smart. SenixVIEW PC Software

SenixVIEW is included at no charge, runs on a Windows PC and connects to sensors via a serial data port. Our Setup Kits provide everything needed to connect through a USB port, including power supply, sensor-PC interface and cables. SenixVIEW is not required but adds powerful configuration, test and management capability.

View sensor measurements graphically in several different ways
Over 60 user-adjustable parameters
Built-in data logging, graphing, exporting and statistics facilities
Save & retrieve setups for maintenance and sensor cloning

Sensor Adjustments Give You More Control

Analogs: Slope, distance endpoints, analog value limits
Switches: Setpoints, hysteresis /window features, time delays
All Outputs: Power-on, loss of echo, loss of SYNC responses
Serial Data: Communications and SYNC modes and functions
Measurements: Temperature compensation, sensitivity, data filters, measure rate, gain settings and data processing filters
Adjustments: Stored in sensor memory even when power is off
