Conductivity/TDS Monitor/Controllers 756-757-758-759 models

Conductivity/TDS Monitor/Controllers 756-757-758-759 models

BENEFITS

  • Affordable
  • Ease of Operation
  • Low Maintenance
  • Ensures Product Quality

The unique circuitry of the 750 Series II Conductivity Monitor/controllers guarantees accurate and reliable measurements. Drift-free performance is assured by "field proven" electronics, including automatic DC offset compensation and highly accurate drive voltage.

Since temperature compensation is at the heart of accurate water measurement, all Myron L® Monitor/controllers feature a highly refined and precise TC circuit. This feature perfectly matches the water temperature coefficient as it changes. All models corrected to 25°C. The TC may be disabled to conform with USP requirements.

Built-in electronic calibration allows for fast quality checks without standard solutions.
(Note: for maximum system accuracy standard solutions are recommended).

A push-to-test button makes setpoint checks easy, while the internal alarm set discourages unauthorized adjustments.

Standard on all controller models is a heavy-duty 10 amp output relay, operating on either increasing or decreasing readings. Bright green/red LEDs indicate above or below setpoint readings.

All 750 Series II models feature an IP65/ NEMA 4X water resistant and corrosion-proof rated enclosure. Compact in size at 152 x 122 mm/6 x 4.8 in., they are suitable for panel, bench or surface mounting.

Additional options include a 3 Sensor Input Switch and/or a 3 Range Switch and a Remote Alarm™ model RA.

CUSTOM & OEM MODELS AVAILABLE


CONDUCTIVITY SENSOR #CS51
For 750II & CTCII™ Conductivity/TDS Monitor/controllers

  • Small size enables convenient installation and service.
  • Dual O-ring seals used on all versions for high on-stream reliability.
  • Plastic gland fitting allows removal and replacement without tools.

MODELS: CS51, CS51LC, CS51LS, and CS51R
BENEFITS

  • Economic Value
  • Small, Convenient Size
  • 100 psi at 100°C
  • General Purpose Use
  • Field Replaceable

DESCRIPTION
Wetted materials of construction are 316 stainless steel and Teflon®**, with double O-ring seals at all points. The first EPR O-ring bears the brunt of process interface, allowing the second O-ring to maintain reliable sealing, free from chemical attack. An integral temperature element allows automatic compensation for maximum accuracy. Leads are 10 ft./3 meters standard.
Process connections are made via a bored through swage 3/4" NPT fitting as standard. This fitting may be installed into a line or tank, or may be reversed and connected to a standpipe for use in a submersion configuration.
The CS51 is ideal for general purpose use up to 20,000 μS/ppm.

CONDUCTIVITY SENSOR #CS52
For 750II Conductivity/TDS Monitor/controllers

  • Very compact size for a high probe constant sensor.
  • Dual O-ring seals used on all versions for high on-stream reliability.
  • Thermowell for the temperature element assures rapid response.

MODEL: CS52
BENEFITS

  • Economic Value
  • Small, Convenient Size

  • General Purpose Use
  • Field Replaceable

This sensor has a small footprint for its high probe constant of 10.0. Its size and economical pricing make it ideal for use in various OEM applications, such as skid mount R.O. systems, water treatment units, chemical dilutions, and many more.

DESCRIPTION
Wetted materials of construction are 316 stainless steel and CPVC, with double EPR O-ring seals. The first O-ring is the only one to touch the process fluid, allowing the second O-ring to operate free from chemical attack. The thermowell containing the temperature sensing element in its tip is exposed directly to the stream, assuring rapid automatic compensation for maximum accuracy.
Process connections are 3/4" NPT for insertion, and the back portion is 3/4" stainless steel tubing, which can be gripped by a swage fitting for submersion applications. A Teflon®** insulator is available as an option to the standard CPVC.
