(8) This full line of Tank Level Process and Temperature Controller devices mate to any of our liquid level switches, ultrasonic sensors, thermocouples or RTD temperature sensors.
This common family of interfacing devices offers both a base unit and / or modular chip that can be installed to provide flexibility when input signals vary from one sensor to another. This is the most cost-effective way to manage multiple application needs.
ESM Tank Level Controllers offer universal input capabilities with a 4-digit display for both process and set points. The plug-in module chip design allows for the configuration of one or two input channels for thermocouples, 2- or 3-wire RTDs or analog 0-5 VDC, 0-50 mVDC, 0-10 VDC or ...
(4) Full line of tank level indicators that mate to any of our liquid level switches, ultrasonic sensors, thermocouples or RTD temperature sensors.
This common family of interfacing devices offers both a base unit and/or modular chip options that can be installed to provide flexibility when input signals vary from one sensor to another. This is the most cost-effective way to manage multiple application needs.
ESM Tank Level Indicators are not designed to maintain (control) a process but can be used as high-limit alarm units by virtue of a programmable latch feature. Otherwise, these Level Indicators offer many of the features of the ESM Controllers. These indicators offer dual or multi-point ...
This DPDT relay device provides electrical isolation for all Madison single-level and multi-level liquid level switches switches. Multi-level switches typically require one relay per level. Relay coils are available for 110 VAC, 220 VAC or 12 VDC applications. The isolated output contacts can be used to switch a wide variety of voltages. The relay can be used for solenoid valves, pumps and alarm applications that do not exceed the listed output contact ratings. The 30 amp load rating can eliminate the need for a pump motor starter in some applications.
In addition to this standard product offering, Madison Company offers a full range of relays for custom applications. Our engineers are available to review ...
(3) The R2-type liquid level controllers provide high-level, low-level or bi-level control in a convenient octal plug-in package. Models are available for pump-up or pump down operation. Transformer isolated AC voltage on the probes prevents electrolytic plating. Less than 1/1000 of an amp of current is used to sense the presence of conductive liquid between the probes and common. Onboard sensitivity-adjustable units eliminate false tripping caused by floating debris and foaming agents. Isolated electromechanical relay contacts can be directly connected to the control circuitry or control pumps and solenoids. The R2-type controllers can be used at a distance of up to 500 feet from probes, and twisted pair or shielded cable is ...
(3) The Madison Company ED Series of Loop Powered Display Models are available for either Probe-Mounted or Wall-Mounted applications using most Ultrasonic and Radar Sensor units with 4-20 mA output. Display indicates the percentage full or empty and can be adjusted to indicate 100% at 4 mA or 20 mA by simply moving an internal link. Units are packaged in a compact NEMA 4X enclosure.
(27) Madison Company offers a full line of process controllers, indicators and timer/counters that mate to any of our liquid level switches, ultrasonic sensors, thermocouples or RTD temperature sensors.
This common family of interfacing devices offers both a base unit and modular chip that is inserted to provide flexibility when input signals vary from one sensor to another, plus a common base type. This is the most cost-effective way to maintain a factory-wide system or multiple application needs.
(6) When very low liquid levels (0.19" to 0.31") need to be monitored, a reed switch device can be used. Madison Company’s array of ultra-low-level floats are offered in several standard level switch designs.
The liquid level switch configuration can feature plastic or metal stems for the ultra-low-level floats to ride on. In the case of multi-level switches, the low level indication can be as much as 0.57" lower than a typical barrel float design.
Ultra-low-level floats are available in Kynar for high-purity applications, PBT or Buna-N for hydrocarbon liquids and FDA-approved polypropylene for food applications and general purpose liquids.
With this unique ultra-low-level monitoring ability, these switches make more ...
(5) For special applications, such as detecting water in a petroleum product, three full-size Buna-N interface floats with different specific gravities are available. For detection of dissimilar fluids that are not petroleum-based, specially weighted full-size interface floats are available in polypropylene or stainless steel.
The Madison Model PD765 Trident Meter is a Universal Panel Meter that handles all of the common process display applications with simplicity, reliability, accuracy and ease. It is factory calibrated to accept process voltage and current inputs, 100 ohm platinum RTDs and the four most common thermocouples. Setup and programming are a jumper-free, single-switch snap using a simple four-button programming method or a computer. If there are multiple meters to be programmed, the Trident’s copy capability allows one meter’s setup to be automatically copied to another.
