Built-in electronic calibration allows for fast quality checks.
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 readings above or below setpoint.
Digital and Analog 750 Series II models have an IP65/NEMA 4X water-resistant & corrosion-proof rated enclosure. At 152 x 122 mm/6 x 4.8 in., all models 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.
Resistivity Sensors
All 750 Series II Resistivity models require a CS10 series sensor. This reliable sensor features two integral thermistors to ensure accurate and rapid automatic temperature compensation. The sturdy polypropylene standard bushing is modular for easy, inexpensive replacement. A PVDF or 316 stainless steel bushing can also be ordered. The metal portion is available in either 316 stainless steel (standard) or titanium.
Note: Special Order, CS40 and CS41, High Temperature/High Pressure sensors available upon request.
