Introduction

OXY 1100 sensor

OXY 4100 transmitter

EVITA® OXY sensors are used for measuring the concentration of dissolved oxygen in water – especially in controlling and monitoring aeration processes in wastewater treatment plants, but also in applications such as ﬁ sh frarms.

EVITA OXY 4100 transmitter and a USC Universal Signal Converter.

There are two versions of the transmitter – a ball ﬂ oat version, OXY 4100, and a probe version, OXY 4150/3150. The operating principle is identical for both versions.

There are three versions of the USC - a USC 5000 basic version, and a USC 6000 with added features, both point to point. A USC 7000 with HART multidrop functionality enabling up to 15 transmitters on only two wires.

The EVITA the oxygen meter. The transmitter converts the measurements by the sensor into a current signal and at the same time also performs the necessary calculations/corrections. The signal converter is the display and programming unit and offers additional outputs.

OXY consists of an OXY 1100 sensor, an

OXY 1100 sensor is the heart of

The EVITA® OXY system offers several advantages:

2-wire transmitter – simple and fast installation

Easy maintenance

– simple automatic calibration in atmospheric

air initiated by using the TILTCAL® or the USC 5000/6000/7000

– self-cleaning ball ﬂ oat – simple sensor replacement after 2-3 years

High reliability

– self-diagnosing – membrane leakage detection – fault indication on transmitter current output

Flexible communication

– HART

communication as standard gives added

features

 setting of measuring range and units from a

distance

 display of dissolved oxygen and temperature,

remaining OXY 1100 sensor life and speciﬁ c event codes

– Option module can be ﬁ tted in the USC

6000/7000 without the need for tools

Mechanical installation

Transmitter

Mounting on a handrail

The mounting bracket for OXY 4100 and 4150 can be mounted directly on a handrail using the supplied hose clips. Retighten the hose clips after a few days use to ensure a tight mounting of the mounting bracket.

In case of strong sideways forces, the PVC pipe should be mounted with supporting wires. This takes up some of the sideways mechanical forces on the pipe and avoids cracking of the mounting bracket.

Pipe mounting

The OXY 4150 transmitter can be mounted in a PVC pipe as shown in ﬁ g. 4.

Mounting of OXY 4150 transmitter using cable bracket

The strength of the transmitter cable is such that the transmitter can be allowed to hang from it.

Bracket (A) is available as accessory supplied by HACH LANGE. However, (B) is not.

Optional add-on module USC 6000/7000

Unpack the add-on module and locate it in the bottom of the signal converter as shown in ﬁ g. 16.

Press the add-on module forward as far as possible. See ﬁ g. 17. Avoid touching the pc board and the sockets.

The add-on module has now been installed and the signal converter is ready to be installed on the terminal box. The menus related to the optional add-on module will automatically become visible and electrical inputs and outputs are automatically established by power on.

Examples of coupling to loop-powered display and PLC/SCADA system are shown in ﬁ g. 22, ﬁ g. 23 and ﬁ g. 24, respectively.

A suitable power supply shall be considered in the end-use application. The power supply must be a Class 2 power source (limited circuit) according to the National Electrical Code (NEC) and provided double/reinforced insulation between mains and the 12-30 V d.c. supply for the oxygen transmitter.

Note: Components like motors, pumps and

computers may cause high voltage potential differences between the protective earth/ ground wire and the water in the tank, that results in unstable readings. If this problem occurs, mount an earthing electrode in the tank to equalise the electrical potential of the water to PE. If the ﬂ ow velocity in the tank is high, it may cause a static potential locally. Is this the case, mount the earthing electrode close to the transmitter.
