LS-1000-BB  Our brass Buna single level sensor is a low cost level switch good for fuel and oil level sensing. The Buna float is light and solid providing a reliable and durable level switch in compatible liquids.

This 90 degree stainless steel float switch is ready for the toughest applications and is highly customizable.  The mounting fitting is arranged to allow the sensor to be mounted from inside the tank or from outside the tank.  Most fitting sizes are available.  There is little limitation on the switch point dimensions, and most float options are available. This rugged sensor works in pressures up to 250 PSI and maximum operating temperatures above 300F. 

This all stainless steel level/temperature sensor is designed for use in the most demanding applications. It can work in pressures up to 750 PSI and maximum operating temperatures above 300F. Like all of our temperature/level sensors, these are available with fixed set point level switches and also Thermocouple, Thermistor and RTD temperature sensors.

Our loop powered 4-20mA sensors are reliable and easy to install.  These sensors will arrive at your plant, ready to install into your equipment.  No calibration is needed.  Simply install into your tank and connect the 2 wires.  That is it.  These sensors are tough.  They are used in demanding applications with years of reliable, accurate performance.  There is no drift and they never need calibration.

Rochester Sensors 9402 Series Guided Wave Radar (GWR, Gen II) transmitter, provides technical advantages over traditional reed switch probe liquid level sensors. The 9402 GWR sensor utilizes digital technology and requires minimal maintenance, while providing high accuracy measurements in mechanically challenging tanks. It features an anodized aluminum head and a stainless-steel waveguide.

Our LD-SP12 is our narrowest standard leak detection sensor. It is designed to fit into your tight interstitial space and only needs a clearance of 1 ¼”.  The stainless steel shroud protects the float from debris and protecting the float operation from being disturbed by making contact with a tank wall or other objects. The internal components include PVC and Nylon, helping to make this sensor a high quality, low cost leak detection sensor.

The stainless steel stem of the LTS-3000-SB improves the compatibility of this low cost temperature/level sensor while maintaining the benefits of the reliable and light Buna float.  These level sensors are available with fixed set point level switches and also Thermocouple, Thermistor and RTD temperature sensors.

Rochester Sensors are available with Cam and Groove Couplings. These fittings allow for the sensor to be very easily installed and easily accessed for cleaning or routine maintenance.  Cam and Groove fittings are matched with an adapter that is mounted in your application.  A typically adapter with male threads for threading into you tank is a TYPE F adapter (not included). Our standard cam and groove fittings are available in: 1 1/2″  Aluminum, 2″ Aluminum or Plastic, 4″ Aluminum, We also stock the 2″ Type F adapter in aluminum.
