Portable PH Meters

The HD2105.1 and HD2105.2 are portable instruments with a large LCD display. They measure the pH and the redox potential (ORP) in mV. They measure the temperature using Pt100 or Pt1000 immersion, penetration or contact probes.

The electrode calibration can be carried out on one, two or three points and the calibration sequence can be chosen from a list of 13 buffers. The temperature probes are fitted with an automatic detection module, with the factory calibration settings already being memorized inside.

Proximity Switches

All switches shown on the left contain reed switch contacts and must be actuated by means of a magnet.

Exceptions are the Vane-Switches, which are actuated by means of a ferrous vane, and the steel sensing Proximity Switches which operate in the presence of ferrous material.

In both cases the switching medium is again a reed contact. All reed switches that are suitable for 240 volts operation meet the requirements of the EMC directives.

Depending upon the type, reed contacts can have an operating life of many billions when used within their specified parameters. Maximum switching power can be up to 230V/3A/100W/VA depending upon type, and Proximity Switches fitted with output cable meet protection class IP67 or IP 68. There are a great variety of standard housings available, but custom housings can also be specified.

Also as standard, there are a number of versions that carry PTB (Ex) approval and which are suitable for all hazardous areas except mines.

Double Setpoint Controller

Double-setpoint controller which increases configurability of series ATR110/120 in the same standard size 32x74mm. Input is configurable for thermocouples type J, K, S, R, PT100, PTC 1000 Ohm, NI100, NTC 10K (typically used in the refrigeration industry) and PT500/PT1000 (widely used in air-conditioning), signals 0...1V, 0...10V, 0...20mA, 4...20mA. Potentiometers 6K Ohm and 150K Ohm may also be read with function "Latch on" for quick calibration and setting of minimum, maximum and zero by frontal keys.

Two setpoints are available, one for command and one for alarm function, and two outputs configurable by parameter as relay or SSR control. The main relay is 8A (on models with internal transformer 24 or 115 or 230Vac) or 10A (on model with internal switching 12...24Vac/Vdc). The alarm relay is 5A. Memory card enables quick configuration, reducing error margin.

Software features include ON/OFF or PID+Autotuning control and Heating-cooling PID with neutral zone. A single output (relay/SSR) version is available with serial communication RS485 and Modbus-RTU / Slave protocol for application with supervisory systems.

All models are CSA-UL approved for the North-American market.
