Littelfuse PC-102CICI-DL:

Dual seal-leak detector uses inputs to sense seal failures and energize the output relay. Input logic direct or inverted is DIP switch selectable.

Littelfuse PC-102CICI-LT:

Seal-leak and over-temperature detector uses one input to sense seal failures and the temperature input to detect motor overheating. Configurable to suit various probes. Seal input logic direct or inverted, plus over-temperature trip reset automatic or manual, is DIP switch selectable. 

Littelfuse PC-102 Pump Protection Controller

Littelfuse PC-102 Description

The LIttelfuse PC-102 series is a dual-channel switch that provides dual protection against seal failures and over-temperature in submersible pumping applications.

The relays have two form-C isolated output relays and two LEDs, which illuminate when each associated output relay is energized.

The sensitivity adjustment (4.7k-100kOhms) allows you to define the input impedance at which the output relays will change state. The sensitivity for the over-temperature detector can be set to 4k Ohms with use of the DIP switches.

5 Channel Pump Controller from Littelfuse - PC-105

PC-105 Series - 5-Channel Pump Controller

from Littelfuse and Flow Factor

For a Quote, Click HERE!

The Littelfuse PC-105 is a 5-channel pump controller designed to handle multiple pump applications. Alternatively, it can operate as a 5-channel switch. The Little Fuse PC-105’s control functions support all of the popular industry standard multi-pump pump-up and pump-down configurations. It can indicate low, high and out-of-sequence alarms and use alternating and non-alternating pump control. The non-alternating pump can be used as a jockey pump or emergency pump. Using the built-in DIP switches, individual pumps can be disabled when taken out of service for repair or maintenance.

Pump Control from Littelfuse - PC-XXX-LLC Series

 Pump Control from Littelfuse in Small Package - Octal Socket

The Littelfuse PC-xxx-LLC-CZ and PC-xxx-LLC-GM series are liquid level control relays used to control conductive liquid pumping operations in a pump-up or pump-down application. The units come in two different voltage ranges (see specs below). The units have an adjustable sensitivity knob (4.7 k to 100 k ohms) that is set according to the resistance level at which you want the probes (sold separately) to sense the conductive liquid. The units have a built-in debounce time delay that prevents the relay from energizing if the probe resistance momentarily goes above or below the sensitivity set point (due to liquid splashing in the tank). The Little Fuse units operate their internal relay based on inputs from a high and low probe and a common reference (when a conductive tank is used) or common probe (when a non-conductive tank is used).

Littelfuse Pump Seal Leak Detector

Leak Detector for Pumps from Flow Factor and Littelfuse

The Littelfuse 460-15-100-SLD Seal Leak Detector Protects pumps from damage.

For a quote please use our contact us form HERE!

Littelfuse Pump Saver Seal Leak Detector

The Littelfuse 460-15-100-SLD is a seal-leak detector to sense seal failures on submersible pumps.

A microcontroller-based relay monitors the shaft seal of a submersible pump motor.  A resistive probe is installed in the sea cavity.  If water leaks into the pump, the resistance measured by the probe decreases. When the resistance drops below the sensitivity set point, the unit will trip and the relay contacts will change state. Output relay logic can be reversed by removing an external jumper.  the unit will automatically reset when the fault is cleared.

Control voltage is 120 VAC
2 form A - SPST contacts
8 amps
IP20  / NEMA 1
LED indicators
UL 508
CE IEC 60947
Din rail or surface mount.

Barksdale BDS3000 Pressure Switch

Los Angeles, CA (March 13, 2019) – Barksdale, a leading manufacturer of industrial controls, is pleased to announce the release of BDS3000, an electronic differential pressure switch with a 4-digit display. The BDS3000 expands Barksdale’s Generation 3000 Series of electronic products that include temperature, level, and pressure sensor technology.
The BDS3000 electronic differential pressure switch was built for filtration systems applications with differential pressure ranges that vary up to 500 psid and with a maximum common pressure of 2,500 psi.
Transmitter functionality is offered via supplying analogue output signals 0 to 10V DC and 4 to 20mA, and is field selectable if needed.  The full scale output can be adjusted to as low as 25% of FSO during installation enabling more flexibility, reducing the need to stock multiple pressure ranges.
The large 14 segment LED angled display is aesthetically pleasing and allows clear readability of the process pressure from multiple viewing angles. Mounting holes are built-in, making it easier to install in various orientations to fit your system needs. Even if the unit must be mounted upside down, the internal software is capable of rotating its display 180°. Plus, the 320° rotatable electrical connection and display housing makes installing the unit very simple, helping reduce installation costs allowing for versatility of installation method and location. Robust EMI protection allows for stable output in today’s factories where EMF and high powered walkie-talkies and VFD’s are present. Additionally, the IP67 class rated housing makes this unit suitable for the wettest of environments, and even full submersion.


  • Measuring range: differential: 0 - 500 psid
  • Enclosure Rating: Type 4X (IP65) / Type 6 (IP67)
  • Two switch points
  • 0.50% accuracy
  • Analog output 4 - 20 mA or 0 - 10 V
  • Superior EMI protection
  • Display & electronic connection: rotatable by 320°
  • Simple navigation menu
  • IO-Link digital communication interface
  • Suitable for rapid cycling applications
  • Hydraulic and pneumatic compatible
